Kakaroto G.SKILL PC4000 2GB HZ testreport

[amrgb]

Mine seem to do 270@2.6v with everything on auto except the main 4 timings. More volts don't seem to have any positive or negative effect.

Overall quite happy with them. They are a good replacement for my Ballistix when they're on RMA.

I'll try to mix them with ballistix when they arrive from RMA for some 4GB goodness

That will be interesting, please list your CPU and mobo when you do

Oh and I have had a good roll on the floor laughing at you sig entries.........classic

[amrgb]

The board is the classic one, DFI NF4 Ultra-D.

The processor is a winnie 3500+, with a very strong memory controller (for a winchester).

It can run 4x512 Gskill LE at 283 2.5-3-3. In fact the limitation is in the board (a different DFI Ultra), since with the new X2 the wall is still at 283.

hi guys, i've buy the gskill pc4000hz 2*1gb
can you give me the setting of bios?
thanks

[hesky]

I don;t have screen, but key settings are 9ns max async and 7ns read preamble.

Drive strength 6 and Data strength 2.

Kakaroto, I've tried those settings and as soon as I set read preamble from auto (5.5ns according to a64 tweaker) to 7ns my system actually fails to post!!

if I run the rest less the read preamble timing, it will end up getting more errors in memtest than when the settings were on auto.

I'm stuck at 265mhz and would love to get to 270mhz. ram is running 2.6v. I really thought these sticks had it in them

this is my setup....

I just got my set of HZ's, and there limit resides at just under 270Mhz 1:1 with my 146 opteron, I'm using the dram settings Techpowerup used when overclocking there hz set.

I'm using the 623.3 bios, can my dram settings be tweaked further more? I'd like to get it stable at 270fsb.

Cheers

edit: it will alway fail dead on 40% in memtest. I've raised the vcore of my cpu even though it is stable at 3ghz with less voltage and I've also ran it at a low 7 multi, but still the same erorrs

swap the sticks around and try again.

Hi, whats the idea behind that mate? pretty curius.

That is correct, when I set 7ns in the BIOS it also won't post. But when you set 7ns in A64tweaker it will work

Btw: is your Trtw at 3?

[perry_78]

Just a thought, would you please include A64 tweaker shots

I've been using 510-2fix until now, but the bios is giving me high multi issues with the uccc i currently have at my disposal. 285 sp1m is no problem with 9x, with 10x no go - mal/preamble/drt settings are being picky

[kakaroto]

Sure, here is my 24/7 setting. Bios 623 official.

Hi kakaroto, so if this value is set in A64 Tweaker and not in the bios it will post? thats pretty random, I will try it asap once I can get to my main pc.

Write to Read Delay is set to 4 so it hopefully yields better stability.
currently have the ram on a divider but it seems to perform 10% worse than when its 1:1 with the cpu, whats the deal with that then? any tips to help this ram out on a divider?

also ben805 said something about swapping the sticks around, anyone know how that will help?

Cheers guy!

[perry_78]

The dfi has one dimm "stronger" than the other. By placing the weaker stick into the stronger dimm slot you should get a more even performance.

dividers impede bandwith, thats about it What kakaroto was saying, is that the setting (at 7ns) works fine, but you CANNOT boot up (i.e. post) with that setting set in bios.

Try switching the sticks, works well with my bh5's!

[hesky]

sweet that makes sense, I'll switch them around asap, Im using the orange slots so I guess the stronger dimm slot is the one furthest from the cpu.

[hesky]

switched them around and now my max is 260mhz opposed to 265mhz must have had it right the 1st time.
doh, looks like I got a poor overclocking pair, I've had value ram with more head room, ah well.

Good work dude

[blazin-asian]

man....i cant even get mine to pass memtest at 270 @ 3-4-4-8 with 2.8 vdimm. im desperately trying to get mine to run 1:1 @ 273 MHz. im using a 9/10 divider now

when i tried Micutzu's settings from the first page it would restart and wouldnt POST with long beeps. had to reset bios to get it running again

help please?

[ozzimark]

sweet that makes sense, I'll switch them around asap, Im using the orange slots so I guess the stronger dimm slot is the one furthest from the cpu.

i've actually found it to be opposite of that

[foodfightr]

sweet that makes sense, I'll switch them around asap, Im using the orange slots so I guess the stronger dimm slot is the one furthest from the cpu.

so you're saying use the yellow slots, or swap the ram in the orange slots?

Can you post a A64tweaker screen please, maybe we can help.

[blazin-asian]

im kind of new to overclocking, but all my settings are done in the BIOS. will a64 tweaker pick up my current settings? thanks. i will post screens when i get back from work.

i joined this forum because i hear the GSkill techs are the best here

[FlyBoyGeo]

Sure, here is my 24/7 setting. Bios 623 official.

So you are only setting your 24/7 settings through windows via A64Tweaker and not in BIOS? Cause no matter what Async Latency or Read Preamble i use in BIOS will never allow me to get past the POST or to windows.

So I guess I am just wondering, are most people just running loose in BIOS and then having A64Tweaker set everything in windows after they reboot?

Thx

wow, AMD Opteron 148 CABYE 0543 FPMW @ 3240? is that with air cooling and divider?
