Asus P5B Deluxe with GSKILL memory setup insturctions and discussion thread

[doakh]

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.

I agree, my best performance is @ 399. It is stable dispite all the problems I have heard about at this level. I wanted to stay on the 1067 strap. I tried 450x8 and it was slower. This is as high as I can go with air cooling. The 7 mulyiplier does not work for me. I cannot get past 475. I guess 610Mhz is the limit for my NB. I ran Orthos for 1/2 hour at 399 and then I stopped it. I'll let it run some other time.

I am currently trying to run at (4:5); 998Mhz (5-5-5-15) but it is not Orthos stable. I can get Orthos to run for only 20 minutes inconsistently. I am at 2.15v for the memory.

you should be able to run 450fsb, 1:1 (DDR2-900) @ 4-4-4-12 with 2.3v. Give 'em a little voltage man!

I have run 450x8, but 399x9 beats it everytime in performance tests. E6600 is limited with PC6400 memory. I should have bought PC8000 or PC8500! My fastest speed came at 399x9 (4:5), so I am trying to make it stable.
I fryed 2x1GB of this ram at 2.40v. It must have been a bad batch.

HAPPY MOTORING!!

[cdelong]

what tests are you using to evaluate performance?

[doakh]

I use Super PI 1M and 32M. I ran Santra, but I am not sure that is really telling me about real life situations. I tried running 3dMark06, but I had trouble getting any results. I am new at this, so I don't know what I was doing wrong. Do you have any suggestions?

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.

Is G.Skill still in the house?

guess not??

[safan80]

maybe he's on vacation.

basically i have no info for you. you already answer all your question. i don;t know how to help you tho

[Cracker]

i think it is your ram.
NQ doesn't overclock good at all and not take voltage either...

value ram it is

Click on the "Is Nice" part of my sig.

I shouldn't have to try and sell your RAM for you but whatever.

1.9v is what it took to achieve this "huge overclock".

[Patriote]

Small question. I have a kit of F2-6400PHU2-2GBHZ which 1 stick just died 2 days ago. I just contacted G.Skill's RMA department to get a RMA #...

I woke up some day, powered the comp and nothing appeared on my LCD... After screwing\playing with the computer for hours (Trying to find the problem...), i found out that 1 of the 2 stick was dead. I tried to boot with each stick separately and only 1 of the 2 would make the comp to boot...

So, my question is, is it really safe to run 2.3v for 1000Mhz 4-4-4-12 for that particular RAM kit ? A good friend of me has his running at 2.35v 1000Mhz 4-4-4-12...

Thanks!

[Patriote]

Any1 ? Pls!

[GSKILL TECH]

well well... the best way to run it is 800 cl4-4-4-12 with 1.9v :P
but to me micron IC.... good overclock always!!! but life of itself is not too long... from DDR we can tell it always like this...

I almost got what you said... So you say that it's normal that the RAM don't live long because of overclocking ?

Thanks for the reply!

for 24/7, i rather use CL5-5-5-15 @ 2v at DDR2 1000. that is kinda safe if you can make it. CL4 and CL5.... well other than super pi... i can't tell the difference

Thanks for the tip. I'll see what gives when i get my kit back from you guys.

BTW: Does overclocking void my warranty?

no it won't

no it won't

Cool

It's again me... Just wondering what sub-timings i should run for 5-5-5-15 2.0v 1000Mhz ? I went through the whole thread and there were so much timings posted... i can't figure out which one i should run for my set-up.

Currently im running 1000Mhz 5-5-5-15-4-42-3-10-5-13 2.0v

Is that any good ? Could such timings refrain me to overclock my new G0 Q6600 on a P5B Deluxe ? Because im having some serious issues overclocking my Q6600 past 3.5Ghz.

Actually, what sub-timings should be run for any DDR2 1000Mhz ram kit ?

Thanks a lot for the help!

3-11-7-13 is the auto setting, micron can go to 3-10-5-10 no problem

it is nothing to do with your CPU overclock, well maybe lower TRRD to 4

Thanks. All thought it's stable @ stable for 400% of memtest @ 1000Mhz 5-5-5-15-4-42-3-10-5-13 2.0v the CPU is still ain't clocking any higher. I tried all sort of voltage combination for NB, FSB, SB etc.. and still the CPU won't do higher than 3.5Ghz stable. I also tried with a stick of D9 i had lying around and it didn't do any better so... Ram is not the problem and im really satisfied with the new kit i got back from you guys. Maybe the P5B Deluxe with latest BIOS is the problem after all. Anyway, Thanks!

Hey G.Skill Technician,

I decide to play around and set my timings as follows:
4-4-4-4-4-20-3-11-7-13 at 2.05v. It is stable per initial Orthos testing. Everything seems to be loading faster than before when I was at 3.6Ghz and 800Mhz (1:1) at stock settings. What is your opinion of this?

ASUS P5B Deluxe (Bios 1212)
E6600 3.0GHz
4x1GB G.Skill F26400PHU2-2GBHZ 833 MHz (4:5)
Sapphire X1950 Pro 512MB

[Patriote]

Am currently running 1030Mhz 2.1v 4-4-4-12-4-42-3-11-7-13 Windows and Bios Memtest stable + Orthos stable too Haven't tried anything else yet. But so far, i like these settings.

I'm wondering what much of a difference do you get by setting a 4 instead of the stock 12 for the fourth timing.

[Netspider]

Hi,

I was using 2x1GB (F2-6400PHU2-2GBHZ) for some time at 835 MHz without problems, now I bought a second pair (also F2-6400PHU2-2GBHZ) and I get memory errors in memtest86+ when I clock the ram at 835 - these problems are gone when the ram is at 668 MHz.

I have a P5B Deluxe and a C2D E6600 (266x9 -> 334x9).
There are no memory errors when I test 1 or 2 of the modules - when I insert all 4 I get errors in the 4th slot (doesn't matter which ram I put there) but sometimes the errors are also in other slots.

I know it sounds like a motherboard problem but maybe someone knows a solution...

btw.: memory remapping is enabled and I'm using the timings seen on page one here

[doakh]

Nerspider....I run 4x1Gb in Vista x64 without any problems. I have easily run 333x9 with my ram at (4:5) 833Mhz with stock settings at 2.05v. I have also run at 400x9 with my ram (1:1) 800 Mhz with stock settings at 2.05v.

ASUS P5B Deluxe (1212)
E6600...3.41Ghz at 486x7
4x1GB G.Skill 6400 HZ 486Mhz (5-5-5-15) at 2.10v
vNB: 1.55
To run stock timings I need 2.35 - 2.40v.
Anyone able to get 500x7 to boot into Windows?
