Well I dropped my memory divider to 9 and so far it has been running longer than before. Im thinking I might need to buy some OCZ Platinum.

Well I dropped my memory divider to 9 and so far it has been running longer than before. Im thinking I might need to buy some OCZ Platinum.
Hi all,
been playing with my new rig about a week now, replaced my shuttle xpc with a dfi sli-dr(latest official bios), X2 4800+, good old 2x512 EB 3700, and a xfx 7800gtx. PSU is Tagan TG580-U22(580W).
I've replaced stock hsf with a zalman reserator I had from previous setup which resulted in a couple degrees lower temps @ load.
Starting from stock voltage and using S&M(latest version supporting dual processors/cores) 2xprime95 and 2xsuperpi 32M for burning purposes and stability testing, managed a stable frequency of 2580MHz.
Upping the Vcore to 1.43(1.4 reported by smart guardian) resulted in a stable frequency of 2712MHz(12x226).
Load temps using S&M(it heats the processor much more than 2x primes, at least in my case) are 54 degrees max for cpu and 55 for pwm(smartguardian readings).
So far so good, I've decided not to try with higher Vcore with this cooling.
Next step was to lower the multi to 11 and try matching the same cpu clock by clocking the memory.
After hours of memtesting and bios tweaking, found the limit of the EBs @ 240Mhz(while maintaining a good unbuffered BW) with 2.9V(from bios). Since I dont use any active cooling on them yet, just coolermaster ramsinks, passing 9 hours of test5 and test8 was a good point to check how this config would do in windows benchmarks.
Here comes the funny part.
Although one instance of superpi 32M would complete without errors, 2 instances would crash the one running on the second core. Running an instance at each core alone, will complete fine.
Same thing happened with primes custom test(I chose custom to test the memory and set 400MB for each instance to use, since blend test uses 768MB, no point running two instances of blend test with 1GB memory), testing each core alone will run fine for hours, but two instances at the same time will crash the one running on the 2nd core.
In superpi case I've set the affinity to each core from task manager, for prime through the advance menu.
Since the crashes on the 2nd core while both cores are tested, occure only when overclocking the memory and not at the 12x226 config, may indicate unstable mem clocks.
I'm not 100% sure though if that's the case, since I dont understand why a single instance of superpi completes without errors and two of them crash. When it comes to memory part, the only difference when running a 2nd instance is that it uses another 268MB of memory.
The same thing is with prime. Testing 768MB with one instance at each core, runs for hours. Assigning 400MB for each instance to use simultaneously, would crush the one running on the 2nd core.
Maybe the answer is that the mem controller is stressed much more while two cores are at load and both of them run a task that involves memory, but I'm a nooby when it comes to A64 setup.
Thanx :)
Thanks man, still running at 2.6ghz and I keep lowering the voltage with no problems. Looks like it was the ram all along.Quote:

I am so pissed.

That memory should OC easily with your setup, mine runs 240 at 1t cas2.5 other timings at default, I have a very similar setup, running 623-2 myself.Quote:

It is after all PC3200, lower latency 1GB sticks "seem" to be tougher to raise the clocks on. I'd really suggest PC4000 sticks, Crucial Ballistix seemingly the best currently.Quote:

Yan
I've tried both slots myself and really didn't see any difference but these boards seem to have a personality of their own sometimes, I am currently running the orange slots though.
I've had two sets of the OCZ 2gb plat kits, the second set I got not long ago even did 235 at CAS2.5 other timings at default so the memory should have a decent amount of headroom left.
Have you tried bumping up your ldt voltage or any of the voltages yet?
I have tried getting dangerous with the voltages... All the way up with the LDT voltage, up to 3.0 volts with the RAM, 1.5 volts for the CPU. What I have found out it, it WILL overclock just a little, I raised the FSB to 205 from the default 200, with the multiplyer on default (11x) and it worked, but since it won't get to the "DMI Pool" thing on 2.4GHz which it did fine with my G.Skill. This must be the RAM, right?? What do you think would be a good plan of action, if this cannot be resolved? Just send this in, and pay another $50 in restocking fees etc. or get a replacement, could it just be that my RAM is retarded somehow?
Thanks!
Yan
Hmmm, I wished I knew of some quick trick to try but the two sets of that ram I have worked without any issues when OC'ing.
I do know that neither set of the plat 2gb kits I have responded to voltage higher than 2.8vdimm so I wouldn't worry about getting to crazy there to achieve good speeds.
Strange, it very well could be the memory, if you just have them exchange it there shouldn't be a restocking fee unless you return them for a different item or credit.
I've never had any problems with mine by just slapping them in, no special tricks or voodoo rituals so there may very well be an issue with the ram.
Have you tried OC'ing using dividers for the ram just to be sure the board and cpu are OC'ing fine?
What do you mean by that? I am still pretty new the the whole overclocking world.Quote:

Hey guys,
Happy to report some good news, I was at 246x11 and now I'm happily at 250x11 (2.75) on my Retail 4400+ :toast: The change occurred from switching XP-120 to XP-90C (should have done a bit better research)
I swapped because my wife's P4-3.2EE @ 3.35 got the XP-90C when I got my XP-120 I noticed her temps went from 114-116'F down to 100-104'F at full load. Thinking my temps were too high on my X2 I switched out and voila 5'C temp drop at the minimum and when I have my room AC on it's even larger up to a 10'C drop if cold enough.
Had issues with video card cooling went from 50'C at idle to 57'C when CPU was at full load this was due to the heat blowing down on HSF (which for my testing was the best cooling method for the CPU. Obviously this hindered my GPU overclock so I now have better positioned fans, my side panel of my case is off currently and I have a 120mm 104CFM fan blowing at the side of the XFX 7800 GTX which allowed me to go to 500/1400 speeds with no artifacts. I was able to bench at 520/1420! highest 3dmarks05 has been 9239
For those wondering single core or dual core and thinking gaming is affected..... The proof is right here in these two urls :fact:
First URL is mine running 250x11 (2.75ghz 4400+)
http://service.futuremark.com/compare?3dm05=1116394
Second URL is a FX-55 SD running 280x10 (2800) Same video almost same clocks on video also
http://service.futuremark.com/compare?3dm05=1046872
Any doubts left out there still about whether to buy single core or dual core, I think it was only gamers that had the dilemma, shouldn't anymore, the only real issue is if you can't OC your 4400+ to 2.6 but at 2532 my X2 was comparing just fine to any 3dMarks05 scores out there :woot:
Note: Don't want to violate any posting regs here but want to help people out, I just found ZZF (Zip Zoom Fly) has the 4400+ Retail for $557 free 2nd day shipping! Lowest price I've seen yet, paid $632 for mine then in one week it went to over $700 at Newegg. With this price available you shouldn't even think about it, but of course that is only if you are shooting for a higher end CPU and you were considering an $800 FX-55, since this is XtremeSystems I assume most people want the best they can get within $$$ reason.
Finally got my 4400+ stable at 240x11 1/1multiplier. Man, I would love to hit 2.7ghz. My temps right now are hitting 48c max. Is that pretty good for air? voltage at 1.43v.
Can somebody explain how I can run 2x SuperPi?
Copy the entire directory. Then run each instance - optionally assign affinity if you want.Quote:

One core failed at 2.75G in 30 min, running only 1 core testing provided no failures.
If I can get dual core priming for several hours before 1 core fails I will probably keep this setting as I don't want to push my vcore any higher and I won't be taxing 2 cores at 100% for hours anytime soon anyway. When I prime just 1 core the temp drop is dramatic usually 5-7c which when testing either core is 100% stable.
Thx, this works :) .Quote:

You can use a divider in the bios, basically you'll do a higher HTT and then use the divider to lower the ram down to whatever you can get close to your max, wish I could tell you what divider settings to use but I haven't done so and this is my first AMD rig all others have been Intel and I never used dividers because the last few CPUs weren't great overclockers.Quote:

Oh and what ram is that you are using? Maybe you could loosen the timings a bit? Are they 1GB modules? For me I'm running 2x1GB ballistix tracers and they paid off bigtime was able to bench them at 289 but stable was around 282 unfortunately my chip doesn't seem to like the 10x multi so I backed down HTT and raised to it's normal 11x and got excellent results
I'm using OCZ VX value. I'm seriously considering going with different ram.Quote:
