I've already passed Memtest86+ (10 passes at each speed) @ 800 (3-3-3-9 @ 2.3V), 1000 (4-4-4-10 2.35V) & 1100 (5-5-5-15 @ 2.4V). And yes, I do have active cooling. OCZ memory cooler. I think I might even try these at reduced voltages, but I think my intent (once I figure out my CPU OC) is to run somewhere between 800 & 900, unless I get some good benchmarks running a divider.

In all three instances I used 4-42-10-10-10-10 sub-timings. A few questions:

Would I be better at 3-3-3-8 at 800?

And what sub-timings would be optimal at each speed?

Oh, I'm running a E6400 Conroe B2 on my P5B Deluxe (0910 bios).

Again, this is some GREAT RAM!!! I am so very pleased with the initial results!

try the 4-42-4-10-6-10 for micron chip
using 1000 4-4-4-10 i suggest

thank you

My Problem:

Memtest Errors when i use these settings ( 2 x GBNQ modules)
DDR2 800,1.9v or 2,0v 5-5-5-15-4-42-3-11-7-13

When i test the modules seperate, Memtest runs with no errors(3runs).

Is that a problem of the P965 chipset?

Greetings Tobias
(excuse my bad english)

you test with DOS memtest or windows memtest?

i don't really know that. you probably need to test it out

Okay, thanks, I'll try the 4-42-4-10-6-10 sub-timings. And yes, it's the Micron D9 ICs. I forget the exact week, but they were manufactured late last year and they use the newer S/N scheme.

i can't even get close to 1000mhz :(
i need to bump up to Cas5 to reach 1000mhz.

^^ignore me. nb voltage was too low for multiplier i was using. currently testing at 484mhz 4-4-4-12-4-42-3-9-6-9 3.4vdimm (3.35actual)

Hey itznfb, let me know how those sub-timings work out for you. I think I'm stable at DDR1000 4-4-4-6-4-42-4-10-6-10 @ 2.3v. 47 passes through Memtest86+ tests 1-8 no errors. Running Orthos Blend to verify. I might even hammer it after that with Memtest test 5. I think that's the one that really shakes the memory down and is most likely to turn up errors?

3-9-6-9 worked for me at DDR800 CAS 3 but I didn't think to try them at DDR1000 CAS 4.

0609 is beta

Can you post the exact timings (sub timings) and voltages (mem,chipset...)

I have problem. At 500 fsb - 1000mhz pc don't start :( I tested alot of timings but doesn't work. Why ?

I have 6400PHU2-2GBHZ ...

for 500 you probably wanna try 7-12-8-12 then 6-11-7-11

I recently bought F2-6400CL4D-2GBPK
Right now it runs at stock 800MHz, 1.9V,
timings 4-4-4-4-2-30-3-9-6-9.

It's memtest86+ stable and 24/7 folding stable. Is it safe to run memory at such timings?
I got a nice bump in memory benchmarks @ Everest, so I would prefer to keep these timings over suggested 4-4-4-12-4-42-3-11-7-13.

By the way what's the lowest possible timings on these sticks? Could it go even lower? I am a bit scared to try it myself.

I just wonder about tRAS, why everyone use 10-15, when it works fine with 4?
Or probably MB fixing it back to 12, thats why it's working?
tRAS should be a sum of previous three timings, right?

using F2-6400CL4D-2GBPK ---DDR2 800 4-4-4-12 1.9V

With a P5B Deluxe, had to go to 1.95V to past memtest86+ v1.55. Failed one on test #4 and one on #5 @ 1.90V. After bumping to 1.95V no errors.

stability

My G.Skill memory passed memtest. Does that means it is 100 % sure that my RAM will not be the cause of instability in my overclocked system? I have the PK stick, I'm using the recommended timings given in this topic. But my ram is running at 416,7 MHz.

Need help!

Heyho, hello!

I've got an Asus P5B mainboard (bios 1202) and 4x1GB F2-6400CL5D-2GBNQ G-Skill Memory.
I already know that Windows XP can't adress more than about 3,25 GB memory and I already switched my chipset timings in the bios manually to
5-5-5-15-4-42-3-11-7-13; ddr2-800 and voltage 1.90V for the memory...at the moment I run the board only with 2GB in dual channel and with these timings the system seems to be stable and runs well---
My wish is to get the most possible ram amount to work, just because I am working with music progs on the pc and every single mb of ram memory counts...or the fastest and best possibility I can get......problem is that the bios (not only windows or anything, both OS and BIOS!!) just says there are 2688MB of memory either there are 3 or 4 GB in the slots....and I do not know if there is any dual-channel mode left when there are only 3 chips in it or if I need 4 of them to have the best solution or...arrggghh!
Please...someone with more knowledge needed!

Thx for your help in advance...Cya!

P.S. Vista is no solution, coz the music progs do not run on this OS!

Hi.

Had a search but could not find a definitive answer. Could someone tell me if 2GB 6400 HZ kits with serial numbers starting in 633.... are DEFINITELY D9 based?

Many thanks

please enable the memory remapping, under bios/chipset i believe

windows memtest if you can do over 300% it should be no problem

Hi,

I have a P5B Deluxe with a Q6600@3200 and 4x1GB G.Skill GBPK RAM. I would like to know:

1) Should I use the timmings posted in the first page or loosen them a bit?

2) Should I increase their voltages?

3) I want to oc them a bit and get 900-1000. With 2 sticks and the E6600 I could get 975 @ 4-4-4-12-6-42-10-20-10-20 but now...it is just not happening. Any tips?

Thx in advance :D

Get a 2*1Gb kit of 6400 HZ on a P5B deluxe. No overclocking

During the first install, the system had boot with all bios settings to auto.

After 3 weeks, the system give me a BSOD and the only for me to reboot is to use another memory module and put Vddr to 2.1v. 3 days later, need to put vddr to 2.25v to be able to boot. Is it a normal behaviour or i miss something ?

4-4-4-12-4-42-9-11-7-13, vddr 2.25, e6600 266Mhz, 400Mhz for memory all other settings to default.

I just changed USB legacy to disable.

My system runs fine with a no name memory and when i'm able to boot with my gskill kit, i can run memtest for windows 600% without an error.

PS: No boot is no beep, screen black, fans on. If i remove the memory modules, the motherboard beeps.

I want to stay on the 1066 strap for my P5B Dlx, which I gather is under 400 FSB. Is it possible to run a (2:3) frequency per the following: I tried and did not get a post.
I have G.Skill F2-6400PHU2-2GBHZ. I like this memory; it seems to work at tight settings.

P5B Deluxe (Bios 1101)
6600......375 FSB running at 3.38Ghz
4x1Gb at (4:5).....running at 938Mhz (4-4-4-12-4-12-3-11-7-13)
vMemory: 2.25
Vcore: 1.40
vNB: 1.45
vSB: 1.60
vICH: 1.057

It was not stable with this setup at 380-390 FSB, but at 375 FSB is was a breeze. This appears to be a sweet spot.

Thanks

I've been playing with this HZ kit for a few days now... not really seeing a difference between 4-4-4-12-10-10-10-10 running a 440x8, 1:1, or 425x8, 5-5-5-15-10-10-10, 4:5 (w/ DDR2-1066mhz ). Both @ 2.3v.

SuperPi is within a few tenths but 440 @ 1:1 wins every time. I thought maybe the extra memory bandwidth might take over running looser timings, but not so.... maybe because I have to drop 100mhz on the CPU to do it. Memory will not cut more than 1066mhz, so my CPU takes a hit running 4:5.

I'm just trying to find that sweet spot..... any tips?? CPU is tapped out at stabilty wise @ 3.56- 3.57g, so I back it down to 3.52- 3.53g for daily use. Rig does not like FSB around 400 just like everyone else. I tried 390x9, 4:5 divider, but it craps out in a few minutes w/ Orthos blend (has to be FSB strap related). I was really hoping to hit between 390- 400fsb @ 4:5 to push everything. I could try 375ish but thats just killing the CPU mhz.
