I have bought an HP firebird 802 but i have a problem with xeon cpu and ram... I'd like to updare a 16gb 2x8Gb but are out stock... have a sigla of your memory card ?
87/5000
I can not find DDR2 memories above 4GB. Where did you buy them? I'm not.ecc right?
Back in the day of DDR2 they went to FBDIMMs for server and 2 CPU workstation memory. So no need for 8GB DDR2 modules. I don't think they exist. Non ECC 4 GB modules are hard to find if you need low density x64 type. ASFAIK 8GB non ECC modules are a DDR3 thing.

Here's my LGA771 swap.
https://www.userbenchmark.com/System/Dell-OptiPlex-380/1942
Dell Optiplex 380 BTX Mini Tower, X5470,8GB DDR3 1066,SSD, and GTX1060 3GB
The 32% CPU rating is becuase it's being compared to dual CPU systems.

I was having fan @ 100% issues that I thought were from the BIOS "unsupported CPU" error. But they were only happeneing at wake from sleep in Windows.
I booted a Linux Live DVD to confirm this and it was Windows related.
Since the SetFSB OC wasn't getting me very much I decided to try undervolting it. Throttlestop 6.00 got it down to 1.1125V. 59*C. running P95 smallFFTs.
I saved that to BIOS from in Windows. Then in HWInfo64 I used the fan controller option to set a manual 1100RPM fan speed which =62*C. smallFFT.
I still need to hit F1 at boot. But no Dell BIOS modding required.

I've been a fan of Throttlestop software for overclocking locked BIOS computers for several years now. I've also found it useful a couple of times in my Xeon swap on a locked BIOS Dell. Throttlestop 6.00 is the version that's appropriate for LGA775/771 CPUs.
I was already running a 1067A LGA775 CPU. So my BIOS had compatible microcode, and useful setting applied. I taped my Xeon and the BIOS would not accept new settings from the 'Incompatable Processor", and ran at the old speed and Voltage. Throttlestop let me raise Voltage to the maximum 1.2500V. for that CPU, and raise the multiplier from 8.5 to 10. It also saved these setting to BIOS. CPU error hit F1 issue remains. But no Dell BIOS mod required.
The next thing it helped with was 100% fan speed in Windows when waking. I had raised the Voltage for some SetFSB overclocking but the G41 chipset wouldn't go past 340fsb, so not much point in that. I started undervolting with TS 6.00 to limit the need for PWM fan control. 1.1125V. stable @ 59*C. PWM fan. I used HWInfo64 to set a manual 1100RPM fan speed and got 62*C. stable running Small FFTs. I could do a custom profile but this Dell fan idles at 1000 rpm anyway.
So if you can't find a BIOS mod you might give this a try.

I didn't notice in the earlier post if you were getting sse4.1 without the bios mod on the xeon?(that's 1 reason most of us need to mod,to enable the rest of the features of the cpu)

I will check for that. I had an R0 stepping 1067A CPU before. But I don't know if I had it before. In some ways the X5470 is a step back from the Q9505S.
The BIOS mod isn't out of the question. I just thought I would post what I found using other methods. I did a GPU swap in the middle of this also.

I did the BIOS Mod. I had missed a final step the first try. SSE4.1 wasn't there, it is now. Some of the benchmarks run a little better.
So the end result Dell Optiplex 380 MT X5470,8GB DDR3 1066 RAM,240GB SSD (on SATA2), and GTX10603GB.
With the BIOS Mods.com patched BIOS no Windows fan issue. Prime 95 stable at 1.1125V. 62*C.
Patched BIOS and The socket modded LGA7771 is all it takes for an Optiplex 380 Xeon swap.
The stock PSU can handle a GTX1050Ti.
SetFSB supports the PLL but it freezes with just a few MHz applied. Typical of G41 systems I guess.
Mini Tower needs cooler J9761
Desktop cooler is 0H7445
SFF cooler is JP911

Intel DG31PR and Xeon E5440

I have updated the board to the most recent bios (2010), but this processor still wont work, just the power supply and board LED (CPU fan doesn't spin) show signs of life. In this thread there are positives for E5420 and E5450, but I would expect this 'in between' processor to work too.

Do I need to insert some microcode into the bios?

Well I had a strong run with my 771->775 setups! 680i mobo spit some capacitors on one of the machines and the other I haven't had a chance to open yet.

Upgraded to an i5 9600K, still considering ordering caps and getting the 680i back alive as it was a quick machine for the value.

I have a SE7230NH1-E serverboard with an Intel E7230 Chipset. The board officially supports Pentium D & 4's but I want to upgrade it to a Core 2 processor. Are there microcode mods similar to the Socket 771 Xeon bios mods for 775 boards. Here's my bios files with the release notes, thank you.
Here is a page with the directions and files that contain both the 771 AND the 775 cpu microcodes. Not sure how well it'll work 4 you because it looks like U have an intel bios & they're pretty much locked. https://www.delidded.com/lga-771-xeon-microcode/

I ran my Dell Optiplex 380, X5470, 8GB DDR3,GTX1060 3GB at Superposition. I did OC the GPU, and bumped the CPU to 3.37GHz. Scored 8115 in 1080P Medium chart.
https://benchmark.unigine.com/leaderboards/superposition/1.x/1080p-medium/single-gpu/page-25
It's interesting to see all the newer i5, i7, and Ryzens at the same level. Some with the same GPU.
But still, it IS on page 25 of their 3rd tier leaderboard. I paid $20 for the computer and aside from the GPU I had the rest of the stuff laying around.

Mobo-Voltage Settings for X5470

Hi guys

Mobo is MSI P43neo, CPU is X5470, RAM are 2 sets of KHX6400D2/4G, so 8GB altogether.

I upgraded my pc some six months ago and went from Q8300 to X5470. Applying the sticker, adjusting the microcode and flashing the Bios was a piece of cake and from the beginning I ran the CPU at 4GHz with the board running at a max FSB setting of 400MHz. Of course I upgraded the heat exchanger as well and put in a tower cooler, so I do not have any problems with the temperature of the cores. After running the CPU stress test that comes with GPU-Z, after running the Intel Burn Test and after running the system for half a year without any problem, I was quite sure that indeed I do not have a problem.

After trying to run Prime95 a few days ago, however, it immediately crashed (Prime, not Windows) with indicating a hardware failure. The first thing I did was to set the FSB to 333MHz. As a result, Prime95 runs properly now but as I do want to let the system run at full speed: could you please help me with the voltages settings I would have to set in Bios?

CPU voltage I would set to 1.25 and DRAM Voltage I would set to 1.4 (please correct me if I am wrong), as indicated in another thread that I have found earlier, however, do I have to worry about the other settings listed in Bios (CPU GTL REF0 und REF1, MCH Voltage, VTT FSB Voltage and ICH Voltage)?

At the moment, all values are set to AUTO.

Thanks
Theo

IMO forget trying to get "Prime Stable".. I don't argue that it is a high level of stability however the truth is that the workload is completely unrealistic and represents the maximum you could possibly ever load a CPU... If you ran just fine for a year without "Prime stable" then delete Prime, enjoy the overclock and never look back :) (of course if you had issues, that's another story)

If you insist, typically you'll need to isolate what is causing your instability.. MEMORY (more often than not, this is the culprit), CPU, BUS SPEED, THERMALS.. Set your memory timing manually per spec of the DIMMs. Try 2T initially. Reduce the memory speed way down lower than it is rated for.... essentially as low as you can go... (ideally unlink the memory from the bus). This can help you determine if an overclock is memory related or not. Memory tweaking should always be the LAST thing you fiddle with and the first thing to cause instability. Focus on getting the best BUS/CPU overclock combination and then introduce memory tweaking days/weeks later. 1.25v is barely enough to get things stable enough for a decent overclock. Increasing the CPU voltage is where you would start. Use LLC if your board has the option. You can go up to 1.4v on CPU as long as you monitor temps and keep them below 80C. I jammed 1.4v-1.45v into mine for about 8 years without issue or degradation but I was also on water. Watching the temps under load is key.

Keep in mind the memory controller is part of the Northbridge so as you push speeds it is common to have to increase the NB voltage a little bit also.

It's trial an error, grab a notepad and document each change.

PS. Forget Prime95.. delete it. Lol.. I chased "phantom" problems for countless hours (specifically with my X5470) and it was very simple.. The solution was that if I wanted "Prime stable" I had to significantly reduce my "otherwise stable with EVERYTHING else" overclock just to pass Prime.. Hours and hours and hours of banging my head.. for what? I never had a problem with anything else so I learned to stop chasing ghosts :Snorkle: :thumb:

Good luck!

Regarding P95, on a 4 core CPU I kill off one thread of P95 right at the start and just run 3. It loads all 4 cores at about 80-85% which seems realistic to me.I get a better overclock and the stability is good enoufg for gaming and benchmarking purposes. For serious workstation apps. don't overclock, and run the full test load.

I am aware that Prime does stress the CPU at a totally unrealistic level but I was chasing the cause of an instability.

My system kept crashing when gaming. I immediately suspected the GPU, every benchmark stressing it worked just fine, though. Took me some time to verify the GPUs bios as the culprit and after discovering an undocumented switch on it and going to the backup-bios, the system is stable when gaming, now.

Prime went on crashing so I increased the CPU voltage to 1.315V and the FSB to 1.4V. Moreover, I have altered the gtl/vtt/mch settings a bit so I was able to slightly lower the cpu voltage. It is much more stable now, with the temperature gauge rising to 72°C after a few minutes of Prime.

You jammed 1.45V into your X5470 without degradation for eight years? Good to know that there still is a slight tolerance but I will stop meddling with the settings, as the system is working quite fine and my heat exchanger apparently has reached its limit, too.

Seems that the increase of the voltage setting was necessary, though. Even when the only other thing that is working stable now is Prime, which I will stop using ;). I am planning to build a completely new system over the next couple of weeks anyway, so anything I do with my X5470 is purely just for fun :D

Thanks for your help!
