Q: Workstation Z440 - Xeon CPU E5 1650 v3 - Fix clock Rate

Hi all, My client owns a HP Workstation Z400 Worstation:CPU: Intel Xeon CPU E5 1650 v3 3.50GHzRAM: 16 GBGPU: Nvidia GeForce GTX 960 2GBHDD I need to change the configuration of the Workstation such that the CPU clock rate will always be 100% (3.5 GHz).I have disabled the Intel Turbo Boost Technology in the BIOS.In Windows 7, I have set the "Power plan" to "High Performance" When I look at the clock rate with the "CPU-Z" utility, I see the clock rate switching between 3.5GHz and 1.2GHz. Are there other settings in the BIOS I should change to fix the CPU clock rate to 3.5GHz? Thanks!Serge

Preferred Solution: Workstation Z440 - Xeon CPU E5 1650 v3 - Fix clock Rate

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I recently acquired a Z420 Workstation. I have flashed the BIOS from 3.88 to 3.90, I have noticed that there doesn't seem to be any automatic fan control settings and the CPU package is getting to 80 degrees during benchmark testing. I have cleaned and changed out the TIM. I can increase the speed manually in the BIOS. But is that relly the solution? Shouldn't this have fan throttling? I have yet to update the firmware. Additionally, dose anyone know the safe maximum operating temperature for this CPU?And yes. I applied the TIM correctly. The fans just not moving quickly enough. Cools nicely when i crank the fan manually. Thanks for your input!! E5-1650 3.2Ghz16GB 1333 2x8RAID0 OCZ SSDsWindows 10 proNvidia GTX970SC

The HP Z440 uses a motherboard designed by HP specifically for the Z440.  It is not a third-party board that is sold elsewhere.  The Z440 BIOS was developed by HP specifically for this system.  HP does not support overclocking, since it could potentially reduce the system's design life goals.

I built this system in 2006, it had been running XP x64 without a problem, the s/w the customer uses, Solidworks, required the PC to be upgraded to Win 7 Pro x64 in April. He has been having consistent problems even after replacing the hard drives, the power supply and checking the ram.

Here is the config:
Supermicro X7DA8 (latest BIOS)
2 x Xeon 5160 CPUs
8 x Mushkin 2GB FB-DIMM
PNY Quadro FX 5000
2 x Adata 256GB SSD
1 x WD 500GB Green Drive (Backups)
Seasonic X-1050 1050W PS

No Overclocking!

I recently reloaded the system (again) after installing the SSDs, I used minimal drivers, just the audio and suggested Nvidia drivers recommended by Solidworks. I did not load any chipset drivers because I found that caused serious file transfer issues.

The system randomly gets BSOD, sometimes when working, sometimes when the PC is idle. Also after a fresh load of Windows that I did offsite, I had no issues while loading the PC (well none that I could not address) but once I returned the PC to his office, it BSOD the first boot. We removed his UPS and the PC booted fine, but the problems were just beginning. My guess is the hardware is just not compatible with Win 7 since we had zero issues with XP. Also I did test the RAM, but I can do it again.

Thanks for the help, this one has been driving me crazy.

I've been having a series of crashes on my Z420 whilst rendering 3D models and generally whilst using the 3D software (cinema 4D). It's using 100% of all 8 cores when rendering and it overheats and crashes, with no notice. I'm wanting to look into the HP liquid cooling solution but I can't find it anywhere online, I've really not got a clue where to get it from and I'm really hoping someone can help me out here by pointing out where to get them because I can't even find anything on the HP site? I'm not willing to alter the affinity of cinema 4D to less cores because I'm told by the IT guy it will just overheat it anyway and it will be at 100% for longer which could lead to huge problems. Oh and software that throttles processes won't work because I'm on windows 7. All help will be massively appreciated!

A:HP Z420 Workstation liquid cooling soloution for Intel Xeon ...

Hi, HP does offer liquid cooling for some workstations. You might want to contact HP Support or HP Sales for availability of water cooling for your particular model Z420. Review this manual page 6. The E5-1620 only has four cores (eight threads using hyperthreading).  Review the above referenced manual page 3.  Check with the application software manufacturer and find out what they suggest for helping with your issue.  Will a processor with more cores help? Are there other ways and technology (SSD or a faster video card, TELSA GPU processor) that will assist with the rendering process?

Hello! I am a happy owner of Lenovo p50, but i got couple of questions. Firstly, Intel Xeon CPU E3-1505M v5 @ 2.80GHz should have a maximum clock speed of 3.7ghz, but thats not the case. The higher i see it goes is ~3.4ghz. I use Piriform Speccy. I tried some CPU stress tests etc, but the result is around 3.4ghz max clock. The Second question is why my bios menu is all greyed and i cannot change any setting. Yesterday i upgraded the BIOS to the latest N1EET60W (1.33 ) and today i tried to visit the BIOS to check some CPU related settings, but i found that almost every setting is locked and i cannot access it. It might be a security mechanism, but before i enter the menu i got promted to scan my fingerprint so i guess that should be it.

Is it still worth getting this -Sapphire ATI RADEON 8500LE Chipset(PAL, W/O 2nd RAM DAC, 128MB, 250/200, DVI, TV-Out) even though it doesn't have the second ram dac and slower clock rate than normal? (250/200 apposed to 250/250)

I really want a 8500LE or 9000pro, and this is one of the best offers I have found (80 from tekheads.co.uk). Is it worth getting this card, or should I keep looking for a 250/250 version?

Thanks, Innus

A:Oem 8500le DOES have lowered clock rate. Still worth it?

For that amount of money, I would suggest getting a NVidia Geforce4 TI4200.
The MSI has a default core/memory speed of 250/550 and I've been able to get it up to 320/655 which would be over or close to the speed of a $250+ TI4600.

WIll I see any increase in performance in games / general home use?The price for the v2 CPU would be c.a 200 EUR minus whatever I can get by selling my v1 chip (maybe 80 EUR?).Thoughts ?

I checked T3600 and 3610 - the only difference is BIOS firmware, even BIOS chips are the same. T3600 has Intel ME firmware 7th version - that is why Xeon v2 are not recognized by the 3600 system, they need later 8th version of ME. Upgrade of ME formware is a difficult procedure  - You need to fit the size and other attributes of old ME region. The simpliest way would be to read both BIOS chips from 3610 motherboard and clean data region in ME but I don't have any T3610 systems. Another way is to analyze BIOS file for T3610 and drag out the firmware for T3600. If anybody has T3610 - please reply

Hi, Xeon E3-1535M v5 or Xeon E3-1550M v5? Which processor would you recommend? A shop told me, that E3-1535M v5 is no longer available by Lenovo and that Xeon E3-1550M v5 would be the best. Is this true? Thanks for any advice!

I just went onto the Ati website to do some research and I noticed two new cards, the x1650, and x1950. Has anyone heard of these cards?

A:Radeon 1650, and 1950???

This is the first time for me and only because you brought it my attention. They aren't scheduled for release until September. The X1950XTX will be the new flagship model.

On ATI's site I also noticed they are working on a Physics setup using a third graphics card (instead of a dedicated physics card). This card can be different from the primary single graphics card and different from a pair of crossfire cards. Just another way for gamers to spend money.

My friend just purchased a new ATI Radeon 1650 Pro 512mb GFX card. Last week I went over and put it in and ran a couple tests and everything was grand. Last weekend he starting having this issue with his card. These little scratches that looked kinda like tearing would appear on his screen whenever he ran a 3d program. I of course checked the VSync and stuff and nothing seemed wrong with it. A few days later it got so bad that the game would lock up within about 20 seconds of getting into any game.

I then thought hey maybe the card is overheating or something. So I installed ATI tool and underclocked the card's memory. Its now running at about 600mhz core and 280 mhz memory.

Is the card bad? It shows video and such fine its just when it goes into the game that it is bad unless I specifically underclock the memory. Later this week I am going to try the card in my own pc to see if it runs right. Maybe the motherboard isnt compatible with the powerful card or something I dont know.

Any ideas would be appricated,

A:Problems with new ATI Radeon 1650 PRO


Well, at least i know i'm not alone. I thought the graphics card was broken, but know atleast its probably not. Exactly the same happened to you as it did to me. It was working fine at first, then the display went all bad. It works fine but when required to draw, my whole os becomes unstable. I keep on getting a message asking me to disable the device and ask for updated drivers, which are updated. I think radeon must listen to these messages because there is something wrong with this graphics card. The bus i have is 1066, Quad core and the psu 600w so its more than powerfull enough. If i find out what it is i'll post it here.

So if my router is reporting my max line rate is 82 mbit/s but the actual rate getting to the router is 55 mbit/s then what does this suggest ?

An Open Reach engineer did visit to check everything was where it should be both at my home and at the street cabinet. Resulting in moving the router next to the socket where the line comes in to the house, initially the speed was getting around 65mbit/s after he had organised things better.

He did say though the connection may go slower or faster over 10 days, its been a month now.

My ISP is Sky and I am subscribed to Fibre Pro (the best they offer) - their estimate to my house was 70mbit/s.

Since then the highest rate I've seen is 59mbit down and 19mbit up.

So since I've subscribed to the highest speeds Sky will offer me I doubt I'm getting capped.

The internet from outside has been cutting off each sometime around 9pm, maybe theres a bad line somewhere between my house and the cabinet ?

What do you guys think ? What are some possible ideas what's going on ?


A:Router reports much higher max rate than data rate

Shared line problems. It's pretty rare for you to actually get the speed advertised. There's a lot that goes into an internet connection, like the link speed for the devices. Applications that monitor, or check traffic can of course slow it down. But the most common cause is a shared line. For example:

You and 12 of your neighbors order the 100mbit service. Your ISP uses a 1Gbit line for all of you. You can get 100Mbits, as long as 2 of your neighbors aren't using it at all, even if the others are using up all of their speed. But if all 12 are on at the same time, it balances, and some people get a drop in speed.

It's all pretty standard practice with ISPs. As far as the dropoff at 9PM, that's usually caused by a gateway/modem reset. That's when they renew their IP lease. Some even do a full power cycle as well. Check your modem/gatway logs at that time to see if it shows any information about reconnecting (usually the easiest way to tell is the time is incredibly wrong until it gets the correct time from the ISP)

Maybe it's different in the UK for the shared line. Maybe there's not a questionable cloud of "Up to 100MBits!!!***" there with some bullet points saying you won't always get it. But almost every time here, that's the case.

I have a ati radeon sapphire pro 512mb vid card and im having this wierd shutdown problem where everytime i play a game, my pc shuts down soon after. Its not just games, i can be listening to music, or watching a movie. I figure its the video card because i have tested everything else. I know my pc is not over heating because i turned off the overheating temperature in my bios. I also put in another fan that mounts to the motherboard and i can aim it at whatever in my case.I know its not my operating system because it has shut off in the bios before the os has even booted, and i've even formatted and reinstalled windows to double check. I know its not my processor because i have bought a new one and tested it and it still sht down.

According to the downloads site for the Acer Aspire 1650 laptop, it has downloads for these devices and applications:


Card Reader
LAN (wired ethernet)
VGA (graphics)
Wireless LAN

Acer Applications:

NB Manager

You need to download and save and then burn off the drivers and applications to 2 separate CD-R's.

The chipset driver should be installed first and then the computer restarted before installing any other drivers.

Once the necessary drivers have been installed and you've confirmed in the Device Manager that the necessary devices are working, you can install the necessary applications.

Are you 64bit? did you get the driver from creative? did you get a win 7 driver, or was it vista?

Q: Z440

Recently I purchased a Z440 workstation directly from HP with a Z-Cooler installed, but it seems to be acting in an odd manor. When the computer is on, the cooler is quiet, but when the computer goes to sleep, the cooler turns on and off every few minutes. When it turns on, it makes a popping noise through the audio system, and spins up noisily. I ran a thermocouple into it (taped it to the plastic housing of the cooler); the temperature has been ~75 to 80 deg F, running or sleeping. It doesn't show up in device manager. Does it need to go back to HP? I really really really do not want to ship away my computer. TY,-Mark Sorry for posting here, but the website's menu wouldn't let me get beyond this topic level.

Hi,I've a client with a z440 Xeon E5-1603v3 CPU. The application he's running is very CPU-demanding. What upgrade options will work in his machine. I know E5-16xxv3 will work. But the price of a E5-1680v3 is quite disturbing. Seen some E5-2650Lv3 for good price level.

I am trying to compare between two video cards that are very similar, and I'd like some other opinions on which would be the better purchase. The differences are subtle but I am not experienced enough to know how large the effective payout difference will be.

The first card is here:

It is a SAPPHIRE Vapor-X 100273L Radeon HD 4850 1GB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card. The Core Clock is at 650 MHz, the Memory Clock is at 1000 MHz. The final price would be $102.

The second card is here:

It is a HIS H485FM1GH Radeon HD 4850 1GB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card. The Core Clock is at 625 MHz, the Memory Clock is at 1986MHz. The final price would be $109.


My comparison so far is that Card 1 has 25 more MHz Core, but 986 Mhz less Memory Clock.
Warranties are the same.
I cannot truly tell, but it seems like the fan on card 1 is less robust than card 2. Can someone confirm this?
As far as my research has led me, the manufacturers themselves are not very different.
GRAM, SPU's, etc., are all identical between the cards. The main difference is in the two clock speeds.

The most major question is this: will a gain of 25MHz in the core clock be more beneficial to high-end gaming with a loss of 986 MHz in Memory Clock? My gut feeling i... Read more
