G.Skill 2GBHZ PC4000 Preliminary test results w/Opteron 180

[Guido]

Man, im so frustrated...just got this mem and testing it right now
It doesn't even boot into windows at 3-4-4-8 1t at 250mhz
Already send back some corsair 3500LL cause it wouldnt even reach 250mhz at 1t.
Tried different biosses, timings etc wouldnt help.
Tried the corsair before i send it back on a different pc. Also an Asus A8N-E but a amd64 3000+ instead of my 3200+. It could reach 250 and higher on that one but not a lot higher.
Is my memory controller maybe so bad on my amd64 3200+???

sounds more like your MB holding you back at this point. Lower your multi to take that out of the question when testing.

[Guido]

i did...htt multi at 3x
cpu multi lowered too so cpu wouldnt be the bottleneck
gonna try it on a 3000+ setup now

if you try on DFi, it will give you better result.
i have see some ppl have problem to overclock on ASUS mother board.

[Guido]

overclocking ok, but i cant even run it ok at the rated speed
need to lower speeds to 3-4-4-8 2t and the rest at the slowest possible to have it stable in windows...

EDIT:

Memory timings
Memclock index value (MHz): DDR400
CAS latency (Tcl): 3
Min RAS# active time (Tras): 8T
RAS# to CAS# delay (Trcd): 4T
Row precharge Time (Trp): 4T
Row cycle time (Trc): 16T
Row refresh cycle time (Trfc): 24T
Read-to-Write time (Trwt): 5T
Write Recovery time (Twr): 3T
1T/2T Memory timing: 2T

ddr voltage 2.6-2.75v (tried different voltages)
htt mhz = 250 (ddr 500 speed)
cpu multi x9 = 2250mhz (have this amd3000+ tested stable at 2500mhz)
getting errors within 30 secs with prime95 :S
is this a DOA?

will OCZ EL DDR PC-4000 Gold GX XTC 2GB Dual Channel work better with an asus a8n-e + amd64 3200/3000+

[rastaseb]

the best GBHZ are for u.s o/cers...lol
I tried your timings major at 200 divider and even at 270, i can't be stable in windows...bsod
i try to modify the treF at 3120 or 3684 and the read preambule time at 5.5...nothing...

[Major]

This is the best I could obtain using Cas 2.5-4-3-7

Sorry didn't have time for Pi 32m but had two instances of memtest running while Pi 8m was running



working on other tweaks right now, will post results in a few

Today I received my HZ and i am f*cking happy !! I first booted at 250x10, 3-4-4-8-7-14-2-2-2-3 , tref 3120, 8ns / 5.5ns , auto in all the rest. I began upping HTT with clockgen, and i managed to pass SPi 1M at 280x10 with no errors, gave an error at 285. I know, SPi 1M doesn't prove stability. I was using BIOS 704-2BTA so i flashed 510-1Fix and tried again. Right now, 3D super stable @ 265MHz with 2.57v (2.6v in BIOS). I love playing FEAR with absolutely no HD read/write

[rastaseb]

thanks fir giving you timings xeno, i'm gonna try them

[Xenom0rph]

np dude, they're almost default timings.

BTW, what TREF is equivalent to "100 MHz 1.95us" ?? I wanna try it

[bachus_anonym]

Either one of those: 1816 or 3684.

[Major]

I'm using Tref of 3684, its the 4th from the bottom in the DFI NF4 bios.

[rastaseb]

i know but i have somme issues in settings...you're using 166 divider at 265 when you're fully stable

[FlyBoyGeo]

1. Which has been the best BIOS?

2. Yellow or Orange mem slots?

[Xenom0rph]

I'm using 1:1 , so no divider here.

In BIOS terms, i had 704-2BTA when i started using the HZ, then i flashed to 510-1 Fix.

I have been testing for only 3 hours now, i can't get any conclusions yet.

[Xenom0rph]

BTW i'm using orange slots. Also Tref 3684 seems more stable than 1816.

[Xenom0rph]

OK. 265MHz is SPi 32M stable so far. Here you have the screenshot with A64Tweaker

[rastaseb]

have you tried to run asynchrone by using 166 or 180 divider?
i think mine is bad, doesnt' want to go higher tan 254 fully stable

[Guido]

I'm rma'ing mine, dont even run stable at 240mhz

[Major]

I'll bet the guys at G.Skill can help ya if you would contact them, infact anyone not able to get there G.Skill stable should check this forum section out

I hope this helps ya rodman

[rodman]

Yes thank you You were around 2.9GHZ running 265 1 to 1 with 3-4-4-7 timings, correct?

[Major]

yes 265x11 3-4-4-7, single 7800gtx default clocks

[rodman]

Done with settings in sig So tight timings and low bandwidth seem better than high bandwidth and looser timings on the A64s. Or am I still missing something

No your not missing anything, its not a very scientific comparison but yes at the same memory speed lower latency is better.
