Dual Core Opteron Thread #2

[QuietIce]

Well, I hit the wall once again at 2789Mhz with a HTT of 310 at the stock 9x multiplier. I tell ya, this OCZ Platinum is really picky! It doesn't like running any faster than DDR400 speeds. Should I drop the memory divider once again (currently at 133) and try to up the HTT some more?

You bet!!! NOTHING is more important than CPU speed. I'd drop the RAM until you know what the top end on the CPU is going to be. After that you might want to adjust things but maybe not.

RAM speed is a distant second for OC'ing ...

Are you serious? I have a couple of G.Skil PC4800 sticks running at 3-4-4-8 DDR600, along with a 3000+ venice @2.7 GHz... and you honestly say that if I had it running at DDR400 it wouldn't make "that much of a difference"?

I get it, you say that CPU speed matters more than RAM speed, but it doesen't on s939, it matters what both CPU and RAM is set at together

So, if you find out what your max cpu is, and the find out what your max mem is, you can make a controlled attempt at making them work at max together... and I tell you... I used a couple of weeks making my TCCD run at DDR600, damn picky those to, had to cool them actively aswell and run with a lower voltage on both cpu and ram then I thought... CPU 1.4V and RAM 2.7V @ 2.7 GHZ/DDR600 3-4-4-8 aint bad Picky mem though... hate setting the memory!!! Takes forever!!!

You're absolutely right and btw, nice memory clocks. Cpu speed is important and should be maxed, but memory speed can make up for a lot. I'm supprised that you can't get more out of your OCZ platinum. I have the same memory and got DDR 560. OCZ guantees it at 2.8v so I'd up the voltage to 2.8 and then also give it the .3 in the bios. From looking around the forum the most this memory seems to like is 2.9v so I wouldn't go over that. If you haven't already then put a 120 mm fan blowing on the memory. You can lower your cpu clock temporally buy lowering your multi and set the memory at 200 divider. Use clock gen or A64 info to up the memory speed in windows and run something like spi 1M to check the increase. This way you can find the max memory setting.
