[MemoryReaction] G.Skill F2-8000CL5D-4GBPQ - Low in cost, high in speed!

Check tRD...maybe put it up to 9 or 10.

[EnJoY]

ive problems to get this ram 2x2gb stable in memtest+ for 500x8. 1:1

tryed default, 5-6-6-20-72, 6-7-7-20-105 etc eg w/o success

i also tryed some settings from this thread...

any help 8( ?

What voltage and what board are you running? Also, you're making the timings far too lax. Take it slow, tweak 1 step at a time. They should be totally stable however at 5-5-5-15 w/ 52 or higher TRFC and 2.0v or less.

[zlojack]

I found that with the 500 FSB I needed to relax tRD to at least 10 to get these sticks to post. On Auto it bumps it to 13.

[dante`afk]

got the asus p5q-e , see sig enjoy

also tryed higher trfc. wont help

[zlojack]

Try tRD=13.... that's what mine default to on AUTO when I put the FSB to 500.

(When I had these sticks, I sold them now)

[dante`afk]

tRD is the performance level isnt it ? it is on default on 13. same results. i just pushed it to 10 down for the test.

[zlojack]

Yeah...tRD is performance level.

Well, then I don't know what to tell you. You might not be able to get 1:1

[dante`afk]

yay strike

i set my memory manualy in bios up and it works with your settings you told me, just passing 2 hours of blend test BIG THX! 8x500


how should i set it up now to go for more fsb and about 1060 @ ram or 1076 ?

higher trfc / tRD ?

[zlojack]

Well, you might want to check your bandwidth and latency in Everest before relaxing the timings too much. I find when I relax tRD too much, the latency really goes up.

On a P5Q series board, almost certainly 9x445 [5:6] DDR2-1068 will be better than 8x500 1:1.

You'll be able to lower voltages for the mobo, & will be able to run a much lower (tighter) tRD (aka Performance Level) & assuming the RAM can do that speed, much faster RAM too.

You'd want to check Everest to be sure, but i'd expect a properly tweaked 9x445 [5:6] DDR2-1068 to be a much better config than 8x500.

1:1 is not your friend on the P5Qs.

Exactly.

Even though a 500 FSB is an impressive feat, unless you can get the timings out of the memory, you often end up with worse performance than a lower FSB with nice tweaked memory. I run 467 FSB with my memory and get much better bandwidth/latency than if I go to 500.

hehe thanks guys, will test this. blend test errored after 7 hours :/ - memory got still errors im memtest as i saw now

running currently at 9x435 - 440 crashes..

trfc 75 - works memtest passes. but i have ai clock twister for mem on "lighter" - seems to be no performance lose if i run everest memorybench.

in another forum i got told that my ram is broken, i should send it back ?

9x400 - 5:6 - ram@500mhz - no errors in memtest
9x500 - 1:1 - ram@500mhz - full of errors

?

[zlojack]

I doubt very much that your RAM is broken. It puts a lot more strain on the system to run the 500 FSB vs. 400 FSB.

your chipset is limiting you, not the ram.

[dante`afk]

im very disappointed about this chipset is p45 .. asus p5q-e.. should do this w/o problems ?

i run 8x500
small ffts w/o errors
large ffts w/o errors
blend - errors after 1 hour

i rly believe its just about the ram settings.. so i get errors in memtest+

[Isira]

What is your vMCH? You may need to raise it.

[dante`afk]

1.32. tested till 1.4. think more wont be nice for the p45

PM G.SkillTechnician here on the forums, or post in the G.Skill support forums regarding compatibility with your board.

Do you guys think it would be relatively safe to run 2.2V through these sticks if they check out stable in OCCT @ 1130mhz? (bios actually reports 1133mhz).

Fairly heavy PC usage (gaming/watching media, ect). PC isn't on 24/7 all the time, but it can be on for long spells consisting of a few days.

Thanks

ps. Keep in mind I'm in the UK, so for what it's worth room temperature isn't that high usually :P

I would give these chips max 2.1volt for 24/7 use and only with added ram cooling... you got a nice set there, on my P45 they top out around 1090-1100mhz, Mushkins go a bit further...

I would back down to a lower speed... but that's my 5 cents

Yeah I might drop back down to 1066mhz and run at <=2.1v.

1133mhz stable is on auto settings as well, I haven't tried to tighten. Well except from it's running in 5-5-3-15, instead of 5-5-5-15.

I'll see how tight I can get the sticks, then I'll see if I can drop to 2.15v or 2.1v, but I doubt it.

[Audioboxer]

Just ran OCCT with the memory at 1130 @ 2.1V and it finished the 1 hour test as stable.

Not tried to tighten anything.

With running the memory at this speed is it even worth trying to tighten things?

If so, what would you guys try changing below in memset?

Thanks

[ihatbs]

My F2-6400CL5D-4GBPQ does 1000mhz @ 5.5.5.13, 2t, 1.8v
and 800mhz 4.4.4.11, 2t, 1.8v
stable for 1 hour test.

What's the max safe voltage for my kits ?

[kpo6969]

Would anyone know if the TR HR-07 coolers work on these?

As long as they are doubled-sided they would be ok? I wasn't sure on this point. Thanks
