G.Skill DDR500 RAM rocks

I have the Asrock and use a64 tweaker-- but just for the 183 memory divider. All the other settings (set to a GSKILL technician's specs) did nothing for my kit and board.

Did this work for you? I had lock ups & BSODs using A64Tweaker. Do you use the apply at startup option? What did you set TREF as?

If you are prepared to live with any error, regardless of how quickly it is found then there's a risk your computer will fail in real world use, especially if you do intensive stuff for long periods like encoding or gaming. At worst you could end with data corruption on your HDD. As with everything, ignoring an error is down to personal preference. My preference is not to.

Exactly. and the only reason I'm casual about my prime results is I think it's heat-related. Not that that makes it any less severe, but my caseflow seems inadequate so I'm rerunning it now that it's cold outside and the window's open. I've also turned up the speed on the CPU fan.

In my experience, NOTHNG heats up/stresses a system like priming - not gaming, not video encoding (although that comes close), and when either crashes it's because of a coding problem or a driver problem - more often than hardware instability.

I've been priming since last night - Large FFT's on core 1 and blend on core 2. The blend errored out after exactly 8 hours 30 min - that's "stable" for me.

In my test last night, Prime95 crashed after 2 hours at CL2.5 so back to the drawing board for me.

BTW, recommended setting for Async Latency = 7-8 & Read Preamble = 5ns according to a G.SKill technician. Higher numbers than this may give you more stability.

Watch out for A64Tweaker, I couldnt get it to work reliably at all. TREF is very hard to get right & the wrong setting can lead to BSOD & lockups.

stevo - thanks very much for that info - with those settings (Async latency & read preamble) it's 24h+ prime stable. btw mine does cas2.5 up to ~230MHz after that I also have to drop to cas3

Duvie, I'm assuming you're talking about a 2x512MB kit with TCCD sticks in it [Those are the only kind of chips that can do what you're talking about...]

You can NOT compare 2x512MB kits to 2x1GB kits. End of story. The overclockability is COMPLTELY different.

The fact that a number of people [myself included] can hit DDR550 on these things with stock timings/voltage [and sometimes undervolted] is amazing, to say the LEAST.

Go buy a normal kit from OCZ or Corsair, let us know how high they can clock, and how much they cost

i have pc3200 ocz performance 2 x 1GB traded for these over 1 1/2 yrs ago . currently have them at ddr500 speed at timings of 7 4 4 3 2T to me this isnt bad. voltage is at 2.8 volts not certain if it can do lower voltage as i never tried. tested over 15 hrs with memtest #5 error free

I just got mine like a week ago, been playing with it for a while, so far i got 260 @ 3-4-3-8, which is not bad, i think it still got a lil more in it, will play with it b4 going to work...

 

[firewolfsm]

i took it to DDR566 at 2.5V, I don't think that's the limit, just my FSB

I had a 2x1GB Extreme set of the 3-4-4-8 variety. It's good RAM, no doubt... But on certain mobos it will not work. It kicked major butt on my DFI LP UT 250GB, but was completely unstable on my eVGA nF41 SLI board. The GSKILL 2x1GB Extreme PC3200 2-3-2-6 stuff would work fine on the eVGA, but would puke out on my ABIT AT8, where the PC4000 would work just fine. I've discussed this with a few people including a reviewer here at AT, and it's suspected that GSKILL is making the SPD timings on their memory a little excessively tight, and it is affecting the compatability with various mobo/northbridge combinations.

I'm not saying it's bad memory... far from it. On a platform that'll play nice with it, it's fantastic. Just be aware of some platforms that don't play so nice.

the gskill kit that you speak of, uses samsung uccc. im not sure if corsair has uccc, but ocz does have it with their xtc heatspreaders.

overclockability is generally the same in both ocz and skill...260-275ish average at stock timings (3-4-3) or loosened (3-4-4)

now for the second point of my reply, which is the price that you mentioned. the ocz kit can be had for 149.99AR

how much are the gskills?

ocz wins in the end unless the gskills are significantly cheaper (like 30+bux cheaper IMO) cuz ocz has THE BEST customer service and warranty, hands down. even better than another big player, mushkin. i've had experience with both.

do you have a 2x512 kit or a 2x1gb?

if they are 2x1gb you got an above average kit.

I agree OCZ has great CS..when I bought my GSKILL they fair bit cheaper than OCZ..$146 AR

But the Gskill newer chips are not ocing as well if you look around..260 is a good bet..270+ is much more unlikely than before
tinkering with these Samsung UCCC is a pain....

AFAIK the OCZ, GSkill and Corsair DDR500 are all using the samsung chips...and OC arevery close

BTW GSkill stock DDR 500 is 3-4-4-8....not sure on OCZ
My Gskill run 260 3-4-3-8-1t@stock 2.6v(or at least this is auto setting for me)

 

[chinkgai]

ocz stock is 3-4-3

 

[nealh]

I thought that was the case..they may bin slightly better chips but I also thought there vdimm was higher???

Firewolfsm..very nice OC..wondering if you would get 280+ on a dual core chip

BTW what did serial start with..mine was 0603...

 

[chinkgai]

vdimm should not be higher in ocz...but they may cover a larger range...such as 2.6-2.8v as their claimed supported voltage

doesnt matter in the end because uccc likes lower voltage (for me and many others i've read about)


mine does its best between 2.5-2.7

it doesnt like 2.8+

i have an active fan cooling them too

mine maxes out at around 272 at i think 2.6v and i run them daily at around 265 with a divider with only 2.5v



i've since swapped these sticks out after playing with them though because i have ocz platinums 2x1gb that does 242 @ 2.5-3-2 and it performs better in everything at the same cpu speed as with the uccc

did you get them recently? nice OCs
