How's 261 with 2x512 PC3200 EB 2.5-2-2-11 at 3.3v? I wish I could set vdimm lower, but I bought the board with the +3.3v rail modded to the vdimm. I am not complaining, but it would be better for testing if I was able to lower the voltage. I may remove it, and just mod vdimm the normal way, and just raise my +3.3v rail if I need higher vdimm.Quote:

Im quite excited about this RAM if it can get me very high FSB (260+) with decent timings and low volts...
:D
Now on to test max fsb with Cas3.
Ok...so, care to tell us what it is then?Quote:

261 2.5-2-2 my god is that stable ?
pretty much. I can run pifast and can prime for a while, but haven't tried 3D yet. I switched my L2's back in for the night, trying to figure something out, but the EB are going back in tommorow. Will run some more test then, and going to try Cas3.Quote:

Wow that's impressive for PC3200 no matter what anyone says. Those are some nice benchies guys good job on that RAM. If I wasn't running an insanely high FSB I'd give them a run to play with. I'd like to see if those will hit 280+ in the future :-D
On a side note what do you guys turn off for unbuffered just uncheck the buffered tests option or more than just that?
my Geil at 272FSB (everyday speeds) pulls
Buffered
6243
6279
UnBuffered by unclickin that one box
4654
4542
There are 9 boxes to uncheck for an unbuffered Sandra. It's pretty obvious which ones once you see an example. I used to have one..........
i went ahead and assumed that teh 3700 is the same as the 3200 and 3500. i jsut ordered 2*256 of 3700EB. ill have it friday for ny infinty. hopfully either the EB or me friends ZMS im barrowing will give me more fsb! :)
Cool, let us know how she does.
I think you uncheck anything that says "Enable ..." from MMX down, but I'm not sure about SMT/Hyper-Threading. Probably uncheck that too.Quote:

I'm currently running 245x10.5 with timings of 3-3-2-11@3v. My sandra bandwidth is:
3767
3508
Is that good results for 3v through it? You guys seem to be getting that with 2.5-2-2-11 but was that at 3.2v? What tweaks should i do with the timing or anything to try and squeeze it to 250. I don't really feel comfortable running the ram at higher than 3v.
Thanks
Is CPC disabled on the bios that comes as standard? ie, the bios with this feature hidden
Yes, most certainly it is. It was added in later (beta) bioses the option to disable this feature.
So it is disabled on the old bios? I just got the 1/31 and enabled CPC and now my ram won't pass prime 95 at default settings at 200mhz
No - its enabled by default on 11/27 and any other bios that does not have the option to turn it off. If ur board doesn't like a certain bios move on. Although 256Mb sticks I though always did cpc enabled ok.
I am currently testing 5/5 with my second board. I could not get dual channel working on the first at anything other than 200Mhz (sometimes not even then). I am taking this slow since I already jumped in at 250fsb with voltages maxed and it got unstable after a time. I got cpc disabled and cpu interface off and I will see if I can make 250fsb like this with 2 * 256Mb bh-5 with tight timings.
Hmmmm when i updated to the new bios i used Winflash and saved my CMOS realoaded settings. When i load up my fastest setings from the old bios it shows CPC disabled which means its disabled by default, not enabled. I can get 245 like this but i can't even get 200 with CPC enabled. I understand CPC changes timings of the chipset but can someone tell me what exactly it is effecting?
I will wait until someone else chips in on wether the default for bioses is cpc on or off. Actually why is this so important? I am 100% certain that the 11/27 bios and all that do not have the option to turn cpc off will run cpc enabled.
just ran 3dmark 2001 and got about 500 points less so now i'm just confused. Maybe CPC is enabled on the old bioses. i'm getting annoyed now.....
There is one bios which has the reverse of what u set. I think its 12/31 that u enable cpc interface, and its disabled and vice versa.
U can set cpc on or off for most bioses so why is the default setting important?
because i was stable at 245 on the default bios, i think it was 11/27 and this bios doesn't have the CPC setting there at all but on the 1/31 and 1/21 i'm not stable anymore with cpc enabled and with it off i loose 500 3d mark points at around the 18500 point instead of 19100.
Have you tried feeding it more vdd?
I am having the same trouble now. I have turned off cpc to gain stability. I needed more vdd for 3d stability, need to test more and verify that I am stable at 1.8vdd. However if all cpc needs more vdd then I will be happy.
This is becoming a chore:
250 fsb cpu interface aggressive, cpc off
dual channel 2222 11 13/15 eefd
5/5 bios with alpha timings at auto (boots fine with default settings)
2v vore 2.63Ghz barton (this board is giving a higher voltage so I may be stable past 2.65Ghz as tested before)
1.8vdd now for 3d stabillity
3.2 v vdimm (needed 3.1v for 240Mhz)
9800pro at stock, over 19k 3dmark which is better than cpc enabled single channel as on my last board.
Using this I got:Quote:

int alu = 1729 MB/s
float fpu = 1873 MB/s
As above with the same 256Mb sticks.
I think the deal with 12/31 is that either CPC is disabled by default, or it's just broken altogether. It's what made the 512 stick users so happy about getting more FSB until they realized the performance hit they took for disabling CPC. In all versions previously, it's always enabled. In all versions since, it's disabled by default.Quote:

neologan, 1/21 is supposed to be best performer with the most stability. The 5/5 beta also seems to give me equal stability and has a stand-by mode fix with all the extra memory timing options from the 2/17 alphas.
So how fast are you guys able to go with CPC?
