do you ever run super pi? which ram timings gives better pi time for 1M?
running the ram at 270 with 2.9v is gona create a lot more heat. you might be better off running the ram at 215 but you guys know a lot more about ocing than i do

great oc's guys this is amazing

Thanks dragon. The 270 didn't pass mem-*test*-('") so I have tightened the timings to 2.5/3/3/6 1T at 215 MHz (for now ) 2.7v. I'll run Super Pi now. 29s to 1M. 26m 33s 32M.

that pi time is amazing. my 4200 stock at 2.2 is 39s for 1M, i'm up to 2.6 now (running orthos) and it takes 34s

32m in 26m 33s. This is definitely a fast chip and it runs cool to. Idling at 29c now in 71f room. I'm going to try for 3.1GHz.

Eh, no big deal on the 180, it was a pleasant side trip. I'll drop the FX-60 back in and see if I can find 3.1 with it now that I'm on water. It will be very interesting to bench it against a 165 at an equivalent OC. That would be an $800 processor against a $160 processor. I'm betting the 165 will stack up very favorably.

As to what to try with the RAM, I'd loosen up and try for 270+ if it were me, but not at 2.9 v. I'll bet it will run looser on 2.8. If you have the option for 4-4-4-8 1T, I'd even try that.

I'll definitely have to play with the RAM and balance 4/4/4/8 at 270MHZ against 2.5/3/3/6. I won't go to 2T though. It wouldn't run at 3/4/4/8 even at 2.9v but is very happy at the tighter timings down around 215. That's basically overclocked PC3200 Corsair.

On the overclocking front it looks like i have reached the end of this trip. 3106 boots fine but won't run more than 5 minutes at 1.57v. That is too high for my liking anyways. 3050 just failed at 1.55v which is what I had placed as my limit so it looks like the 3006 is the top end for this little chip and that is fine with me. It runs great there at relatively low voltages and the RAM runs on tight timings there as well.

One helluva ride though and an amazing chip. Runs comfortably at 67% over stock. I'll have to do a 20 hour run, I guess, but no biggie, I can always drop a little more voltage in there if it can't make it. Just have to figure out my RAM now. We'll see if Wanna's will go a little higher once he gets his cooling squared away.

As long as it took me to get above 3000 on an FX-60, I'd take 3006 from a processor at 1/4 the price any day of the week! That's a great result, Merc!

Thanks Arlie. It was definitely a new experience for me. I never expected to see this thing go that high.

Which ram is that Merc ?

Cris-
The RAM is Corsair XMS 2048-PC4000 (DDR500). It was a perfect fit for the 240-250 FSB but is a little tough with this chip since it puts me between dividers. The 166 sets it at around 270MHz, which the RAM won't hack, and the 133 sets it at 215MHz. The good thing is at 215MHz I can set the RAM at 2.5/3/3/6 1T, basically XMS PC3200 speeds, and it runs great. Just as good as overclocked PC3200 gaming RAM.

You can check corsair forums for the IC thread, but I think that you're running UCCC chips.

Avoid high voltage and relax latencies to increase clocks.

I run mine at 2.5v, I can run 270Mhz even on 2.46v.

Let's see the IC thread:

TWINX2048-4000PT XMS4000 V1.1 0621169-1 = Samsung -5 TCCC (should crap out at 250Mhz)

(UCCC MODELS BELOW)

TWINX2048-4000PT XMS4000 V1.1 0608017-2 = Samsung -5 Rev C 64M X 8
TWINX2048-4000PT XMS4000 v1.1 0602105-1 = Samsung 64m X 8 Rev C
TWINX2048-4000PT XMS4000 v1.1 0540080-1 = Samsung -5 Rev C 64M X 8

Thanks Cris, I'll check out the RAM when I get home tonight. I tried 4/4/4/8 at 2.8v and it didn't work. I have never really looked at the RAM chips like I do at CPU numbers. I'm not sure if running at relaxed timings (4/6/6/9) at 270MHz would beat tight timings (2.5/3/3/6) at 215MHz. What do you think?

I use 3-4-4-8 and some UCCC can run 290Mhz at these specs.

GsKill HZ is based on UCCC and they posted an internal review of the HZ kit on Xtremesystems:

Almost all -*test*-('")s show the latency timings and more.

If your ram is one of the UCCC based kits it'll not react well to 2.8 or 2.9v.

Based on what you posted earlier, I think that you have a TCCC version, the first 4000 kit.

I haven't tried to boot below 2.7GHZ so I am definitely going to take a look at the numbers when I get home but I have a feeling you are right and it is the TCCC stuff.

Has anyone ever done any benchmarks on this? wold be good to get a definitive answer on this divider/no divider thing
