That's odd, but if it seems to working, hey thumb.gif I'd still run some compatibility tests though with a few monitoring programs to make sure everything is working as it should.

That PLL voltage looks quite high, and you likely just need a hair more vcore, all CPU all different, even same stepping and everything. Just go up one notch and see if it lasts any longer than 2 minutes. I think you could probably drop the PLL down a few notches though...

I suppose you put the new one in at the same time as you replaced the power supply?
Fans and power supplies aside, what's happening with your overclock and also what BIOS are you using with that board?

I was going to put both in at once, and plugged both in on the first boot up. After the black screens I thought better of it and wanted to see if the PSU worked fine first, so removed the card till it did.

I'm on the latest bios, with the most up to date microcodes modded in. No over clocking progress unfortunately, as I've not been in the house much

Since changing to a better PSU my overclock is definitely less stable, can only last about 25 mins on Prime :s Hmmm. And even though it stopped for a while after turning off Fast Boot the PSU is doing the same trick of running its fan for quite a few mins after shut down. That was taken from an AMD powered computer that never exhibited that behaviour before... Any ideas what the deal is, guys?

thermal control on the psu? Also, Is the PSU also showing as chassis 1 in your speedfan?(fan @ 41rpm pwr & chassis1) Not sure how that works,is why I'm asking.If the PSU is only running @ 41,& has a thermal switch on the fan,that would explain why it's running longer with the xeon overclocks,ect.redface.gif and if the psu is overheating,it could cause power fluctuations making the overclock unstable possibly.
post #9616 of 12467
That 41rpm is nonsense, I have monitoring of the psu fan switched off in BIOS, in the hopes it would't report 41rpm pointlessly anymore! haha. It does that just when I attach chassis fans to connectors that are monitored. I'd also love to know what it thinks is spinning at about 16,000rpm! biggrin.gif

It's possible that the computer is making the psu fan keep on running as it thinks it's only running that slow. This PSU is definitely cooler than the last, and I can feel the air moving properly from it.

Anyone have any idea how to patch the bios file if it isn't a ROM? On this MSI motherboard it's a SA0 file, but it's still an AMI bios.

7592vSA.zip 798k .zip file
post #9618 of 12467
Damn, I must have the curse of figuring stuff out right after I ask, all I needed to do was rename the SA0 file to a ROM file and it opened fine...

I just found this website: http://genius239239.myweb.hinet.net/771/

Seems to have modified BIOS for a lot of boards...
post #9620 of 12467
Hi, I'm having a problem with this mod.

I bought a modded Xeon E5450 from eBay and I followed all the instructions to inject the microcode in the BIOS (the first time before doing the BIOS modification step, Windows 10 wouldn't boot, but after that, boots and CPU-Z recognices the Xeon CPU). The problem is that my system reboots itself randomly after the modification and I don't seem to find the cause.

My system specs:

Xeon E5450

Gigabyte GA-965P-DS4

Radeon HD 7850 1GB

4GB RAM Kingston PC-6400 DDR2 800MHz

Nox Urano 500W PSU


I've read in some forums that it could be a problem with the PSU, but after the modification it worked. I've tried reinstalling the modded BIOS and reinstalling Windows 10, but problem persists.

Now I'm trying overvolting CPU to 1.3V and see if it solves the problem.

(Usually, the random reboot occurs while doing heavy stuff like a stress test or gaming, but also sometimes when doing regular stuff).

UPDATE 1: Overvolting didn't solve the problem, I've just run a stress test and the PC just rebooted.
Warning: Spoiler! (Click to show)

UPDATE 2: Stock CPU voltage (1.2V) and disabled CPU Enhanced Halt (C1E), CPU EIST Function and Virtualization in BIOS. CPU crashed with BSOD (KMODE_EXCEPTION_NOT_HANDLED) (This is new).

UPDATE 3: Tried with CPU voltage 1.25V, RAM voltage +0.075V, MCH voltage +0.10V. PCIe frecuency set to 100Mhz and the rest of settings on stock values. PC reboot when doing stress test.

UPDATE 4: Trying stock settings but now I plugged the PSU cable in a different plug. PC reboot while doing stress test.

UPDATE 5: Xeon E5450 working on ArchLinux. Runs Mprime + GPUTest and no random reboot. I think that the problem is related to Windows 10 or the BIOS microcode. Now I'm gonna try with my Core 2 Duo E8400 on Windows 10 and see if it reboots.
Warning: Spoiler! (Click to show)

Core 2 Duo E8400 seems to work fine for the moment.

UPDATE 6: Something weird happened. After testing the Core 2 Duo and checking that worked fine, I put back in the socket my Xeon E5450. Now the PC doesn't reboot (after +20 minutes in stress test) but only 2 cores are detected and runs only at 2.66Ghz. It performs like the Core 2 Duo.
Warning: Spoiler! (Click to show)

I forced Windows to recongnize all 4 cores with this method: https://www.youtube.com/watch?v=bXLDhR1FMqQ

But now my PC reboots again. No solution for now.

UPDATE 7: I've overvolted the CPU over 1.4V. Seems stable but it runs pretty hot. PC REBOOTS
Warning: Spoiler! (Click to show)

UPDATE 8: CPU voltage set to 1.375V, the rest of configuration in stock settings. System not rebooting for now. Seems stable. I'll try to keep lowing the voltage until it gets unstable again. PC REBOOTS
UPDATE 9: Minimun voltage archived without rebooting was 1.35625V but CPU still hot (over 80ºC). Now trying lower voltages and changing other MOBO voltages like MCH and FSB. PC REBOOTS

UPDATE 10: CPU running at 2.66GHz, no reboots, voltages set to AUTO in BIOS. PC REBOOTS
Warning: Spoiler! (Click to show)

At the end, CPU not stable even at 2.66Ghz, PC just rebooted after some time gaming.

UPDATE 11: After getting some BSOD and reboots, I've decided to reinstall Windows 10 and reset the BIOS. After that I've tried different voltages without success. The most stable configuration by now is (1.225V, PCIe 100MHz, 320MHz Bus Speed, SPD 2.5) but I'm getting low performance in games, a lot of stuttering and frame drops. The CPU is running at 2.7GHz.

UPDATE 12: I think I've fixed my performance issue with the Xeon E5450, I followed this steps:

1) Swaped RAM modules.
2) Mod the BIOS again and install it.
3) Also I've followed this tutorial and used this program to use microcode in case BIOS microcode didn't work: https://labs.vmware.com/flings/vmware-cpu-microcode-update-driver#summary*
4) Set BIOS settings to most stable setup.

No FPS drops, no reboots. Smooth 60 ~ 50 FPS gameplay.

*The 3) point I think it works if you DON'T want to mod your BIOS.
