Overclocking EVGA SR-2 with 96GB RAM and Dual Xeon X5690 processors
Overclocking EVGA SR-2 with 96GB RAM and Dual Xeon X5690 processors
Hey there! Let's walk through this together. The issue you're facing is pretty common when trying to push RAM speeds beyond its base rate, especially with ECC memory like DDR3. You're aiming for a stable 1600 MHz, but the current timings suggest you need adjustments.
First, the 9-9-9-24 pattern indicates a high-speed configuration, which is great for performance. To reach 1600 MHz, you'll likely need to tweak the memory timings further. The key here is balancing speed and stability.
Since you're using ECC memory, consider lowering the base frequency slightly (e.g., from 1333 to 1280 or 1290) while keeping the overclock at 1600 MHz. This can help maintain stability without sacrificing too much speed.
Also, ensure your BIOS is set to support higher frequencies and that your motherboard has the necessary features enabled. If you're still hitting issues, try using a different RAM model or check for any firmware updates.
Remember, overclocking ECC memory can be tricky—stick to gradual changes and monitor performance closely. Good luck!
I previously tested my DDR3 Mushkin Redline modules at a voltage of 9-10-9-27-36 with a 1T current.
I'll give it a shot with something similar for the first few numbers. Perhaps increasing all the numbers by about two should work. Regarding the CPU setting, raising it to 1.45 at air speed seems risky—some users are warning about potential issues. Check the latest forum discussions for more insights.
How did you even manage to get an SR2? I think 96GB RAM is more than enough, so just reduce half of it. I don’t know what RAM you actually have—good ones usually handle overclocking well and stable voltage scaling. My extreme DDR2 runs around 2.6V and can hit up to 1270MHz, while my Zepplin DDR2 reaches about 2.4V and goes up to ~1086MHz. Chinese RAMs with Samsung dies rarely exceed 1000MHz and don’t respond well to higher voltages. Maybe try some 2133 or 2400MHz DDR3 sticks like Corsair Dominator Platinum or Trident X. They’re typically 4GB modules, so you can fit a lot of memory into your system. Ideally, keep only one channel active per RAM stick so the IC doesn’t get overloaded.
1.45 is a bit high, but your RAM usage is significant. I tested an X5690 for ten years mostly with a 3x2 kit of STT Chromes. They’re rated for 2000 8-8-8, but I often ran them at 1600 6-6-6 or 1800 7-7-7. Eventually, I moved to some BBSE and ran at 2000 7-9-7, then Z77 at 2133 8-9-8 or 2200 9-10-9. You might want to try 1.45v, just keep an eye on it. You’re probably already monitoring it.
I manage many tasks that rely on 96gbs of RAM, especially when dealing with issues like TensorFlow memory leaks across updates.
Yea, Ryzen would likely be a better choice instead of sticking with an old platform. The SR2 is mostly just collectible or for extreme builds now—it’s not practical for daily use. Could you share the BIOS chip details? (It’s usually close to a CMOS battery.) Maybe I can help you flash SR2 bios on budget server boards, so you don’t need to buy rare MBS. Would you like me to show your current setup with the SR2? Or perhaps you’d prefer some advice on other upgrades? And hey, if you’re feeling creative, a scrap-metal RAM cooler sounds fun! xD
//valid.x86.fr/6yuicm IT WORKS. 96 gigabytes of RAM, clocked at 1660MHz, reaching 4.3GHz in air. VCore:1.3625V, VTT:1.425V. Clock speeds default with 2,3 instead of 1,0 thanks to the special 96GB setup. Cinebench score improved from 3081 to 4066, a gain of about 31.9%.
