Hi!
Time to wake up the topic a little:)
I have the following stuffs:
DFI LP nF4 Ultra-D
3700+ SD. E4 "KACAE 0552"
G.Skill F1-4800DSU2-1GBFF
And i keep getting BSODs at 2.5-3-3-5, 2.5-4-4-8 and any ram settings, even at 250mhz ldt, ram 1:1. Memtest #5 and #8 are 10-20 pass without errors up to 590mhz 2.5-3-3-5. Other ram settings i have tried is the same as in Kakaroto's guide, or what G.Skill technician has wrote in this thread: http://www.xtremesystems.org/forums/...ad.php?t=97680 .
I also tried the same settings as these: http://www.xtremesystems.org/forums/...ad.php?t=66107 .
And no way over ~240mhz 1:1 with ldt. Windows xp boots up, maybe a few minutes ok but then its always the bsod. Prime95 and superpi makes errors after a short time. Or i get bsod already at bootup.
I've tried different bioses like 615-1, 623-3, 623-1, 702-1, 702-3, 329, 704-2BTA but all the same.:(
I've tried the original 275mhz 2.5-3-3-5-7-13 settings, but that neither was stable in windows.
I also tried an other 3700+ cpu, but that was worse then mines, that didnt even enter memtest. Now i've got a 3800+ Venice E6 with the date code of 0630, but it sux, too. Nearly the same "stability" as my 3700+ E4. It's nearly no matter how high VID is. I also varied VMem between 2.68 and 2.88...
The only stable setup is 200-210mhz 2-2-2-5 with both of these cpu's. And also with increased ldt and ram divided back to ~200mhz, it works fine.
What can be the mistake? Or I just have 2 cpu's with trash memory controllers? Has anyone had the same problem?
Thanks for the replies!

@FlasH-BacK: Have you turn down the HT multiplier to 4 or 3. If your HT multiplier is still on 5 the HT will run on 1200MHz for a HTT of 240MHz. This is close to the limit of the HT-Bus and will cause instability when booting into windows.
I have the same problem with my setup, but that has 4x512MB TCCD modules in it and I can not switch Bank Interleave to disable on my Asus A8N-E. Memtest 8 runs fine until I hit the 285MHz, but test 5 will give errors going beyond 250MHz and windows doesn't run stable higher that 240MHz.

I always set ldt back to 3x, that doesnt matter. I start thinking of very bad luck, i've tried it with 6 cpus but nearly all the same. Today there was a little test with a 4200+ x2 toledo with the date code of 0723. It wasn't stable in windows with cl2.5, but with cl3-4-4-8 neither.:shakes:
Four modules are always more problematic, it's not a surprise that 240mhz is the top. By the way, with 2 modules, cl2.5 what's the highest prime stable clock you can achieve?

First off do you have 623-3?I have an Ultra D also, this is my old info that I've been using for almost 2 yrs now, copied the post)
That is what I am using as it worked better in memtest for me(compared to 704-2bta) but windows/prime is unstable @310mhz
I am using Partiot ddr600 xbl tccd's and I am at 300 2.5-3-3-5 1t @2.73v prime stablex2, I can get to windows with the same settings at 310mhz and pass (test 5 and 8, most importand ones imo) in memtest for hours but fails prime so for now I went back to 300
also try 2.7v and enable the +.3v it made mine more stable(I found this by pushing the fsb to the max(312) and running memtest 5 and 8 trying different voltages if there was an error)
give it a try, I understand that mines a little different
here are mine you could try: ltd 3x,
200 1:1,enable, 2.5-3-5-3-9-14-2-2-2-2-3072-1, enable, increase, 0, drivestrength 7, data drive 1, 9ns, normal, 5ns(also try 5.5ns), 32cycls, disable, 16x, 7x, disable( ) bursts. You may want to try this 1st though, 3-3-7-3-10(with the rest above),tras of 5 is more stable than 7 for me, (also the 10 was more stable and is the only thing I had to change from then)I also use 3072 for tref for more stability. You may also have to change the 2's to 3's ?
I have them a little diff but these are very stable for me and I only have a 460W psu w/ many things running. The way I look at it is memtest is a great starting point, if it fails that then it will deff fail in windows while stressing, now if it passes memtest then thats a start because normally it will have to be backed down some from the highest you can do to pass in windows.

dram drive strength should be 1-2 that may help ya.

Thanks for the advices, now i could get it more stable at ldt 300mhz 2.5-4-8-4-9-14-3-2-2-2-3120-1 DQS decrease by 128, vdimm 2.7V in bios.
Actually i'm using a 3800+ X2 toledo and prime95 is stable at 290x10 with 1:1 ram speed. Now i'm trying to get higher.:)
