I'm running 3400 dimm / 3800 uncore and barely get 79000 read / 73000 write!

You must tell me your secret! thumb.gif

Hello

Cache speed isn't everything.

Thread Starter 
I got my memory to 3200mhz and 3700mhz uncore. My timings are 16-18-18-38 1T. I guess I can tighten the timings a little bit.

Can someone please explain why my CPU Voltage always jumps to around 1.296-1.298v when in Adaptive mode...even though I have the OC Voltage set to 1.150v? I'm overclocking to a very modest 4000mhz on my 6850k and I'm running very stable at a manual voltage of 1.180v but as soon as I flip from manual to Adaptive the voltage jumps to 1.298v. I can go up to 42x or 4200mhz and the voltage stays at 1.298v...which is obviously more than I need to run the system in a stable state.

The reason I'm asking is because I'd like to stay in Adaptive mode, but the temperature difference between Adaptive 1.180 and manual 1.180 is 12C...54C for manual and 66C for Adaptive while at the exact same 4000mhz or 40x.

Hello

The adaptive voltage cannot be forced lower than the default VID programmed by Intel.

What what's the best setting for everyday use? All of the articles I've read mention Adaptive as the best option, but that also increases temperatures? Would you stick with manual or just deal with the heat associated with Adaptive?

Just placed an order for the 6950X. Got free over-night shipping to! So, it'll be here Monday. Going to order some pieces to finish up my custom loop, test it out, and then depending on how the new Titan X performs, I'll likely purchase one of those to pair with it!

Manual does not allow for low power states, so what do you think is likely the best option here.

Praz, I fully agree, but he's got the same 8 core 6900K and running the memory at 3200 vs. my 3400! His only advantage is he's 14-14-14 vs. my 14-15-14. That of itself can't make that huge difference.

Which brings me to my sad story. I figured I'd give 14-14-14 anoither go, so set my dimms to 1.45v eventual. GSAT re-booted after 30 seconds. So I said fine, the hell with it, and went back to my previous settings but figured I'd stressapp again while I was there. Got a bunch of errors. Now I can't get better than 3300 no matter what, so looks like I cooked the dimms, which is weird because I had tired 1.45v before (no other voltages were changed).

Hello

Test each stick of memory one at a time using the same slot each time. If all modules pass the issue is not with the memory.

You mean GSAT each module separately? Will Linux boot with 8GB? I guess probably.
