Tightest timings ever?

[Sidebinder]

What can you guys do with your bh-5 mem at pc3200 on nf2? Timings wise. I just did Cas 2-2-1-2 at ddr 400 on my new dfi. Please post yo results. :toast:

[Soulburner]

My ValueRam 2700 will run 1.5-2-2-5 at 166mhz (default). Yes, that's CAS 1.5 ;).

Those are the lowest numbers I have available on the P4PE.

[Drisler]

seriously putting tRAS that low is counter-productive. Never go lower than CAS + tRCD.

[STEvil]

173 2-1-1-5 3.15v with my BH-6 in DC on my 8rda+.

[toolbox]

2-2-2-3
Mushkin value ram Pc-2700. Magic pair.

[eshbach]

i can go 2-2-2-2 2.6v 200fsb on my mushkin l2 3500.

[Stang_Man]

i've done 4-2-2-2 with an 8rda+

[Kalway]

tightest timings would be 1.5-1-1-3. Lets see someone try it. I think only a Via or some Intel chipsets could address those timings. NF2 can't because it's got that wierd ass memory controller.

[Hell-Fire]

Best I could muster was 2-2-2-4 with some HyperX 3500 (BH5).

Do these even do anything? How much of a performance increase (if any) would they offer from like 2-2-2-5?

doesn't look like much. 96% efficiency on an nforce is just average which is what the first poster got.

Another forum I am on had a little contest to see who could get the lowest fsb and still break 3K on Sandra. I think we got down to 192 at 3011. Not to bad for efficiency.

[TheWeaseL]

2-2-2-3

[saaya]

what happened to cas1? there used to be memory around that could run cas1...

anyone care to provide typical efficiency on canterwood? I get 76% but I have no idea if thats good or bad..

sounds nice, bh-3? just kidding. i think i read about that once though, pretty sure there will be cas 1 ddr2, would be some nice ram to play with

[saaya]

ddr2=cas3,cas4 and cas5 ;)

Yes at DDR400, 533, and 800 respectively.

[st0nedpenguin]

Could someone point me in the direction of the formula thing used to calculate optimal timings?

Can't seem to get Google working today.

In dual channel 5:4 I get 86%. At 1:1 I am around 78% and at 3:2 it is around 90%

Which shows you that number is completely useless and not accurate.

[Sidebinder]

Yeah, that number is pretty useless. However, that is the highest I have ever goten at DDR 400. So, I am just going to run it at that for now on. It also gave me some extra 3dmarks in both 2k1 and 2k3.

no basically it shows Sandra as a whole is useless. On an AMD system or Intel in 1:1 though it can give you a gauge to shoot for.

[Kalway]

anyone been able to run CL1.5, RAS to CAS 2, RAS Precharge 1, and TRAS between 4 and 7?

I think that's probably as tight as BH5 or BH6 could go. You'd have to do it on a Granite bay, KT600, KT333, 845PE, 848, or AMD761 chipset. 875, 865, and nforce2 can't handle that tight of timings, to my experience.

That too :D

Well I have a 845PE and I could test....but i'm too lazy...

[skate2snow]

I was thinking the lowest timings was 2-2-2-5, is those that are under that some bugs, or you see a performance diff?

[Slickthellama]

I used to run 1.5-2-1-5 @ ddr 250 on my ol' P4S8X, man that mobo sucked but it could really pump the timings.

Great minds think a like! LOL :D

[STEvil]

768mb BH-6 (3x256) @ 200 2-2-1-5 3.0v right now..

:D

[IamAnoobieCheez]

unrealneo, seems like that extra tight timing of "1" didn't do too much. I get 40 sec @ 225fsb at 2-2-2 and @ same clockspeed as yours.


this is for all ya:

I wouldn't bother with the ram timings below 2. The system nor the memory aren't designed to handle cas 1 or 1.5. It's gonna get unstable even where you at now. Time will come to you and WHAMM.. Mr. unstability...


Not that I'm tryng to rub you guys in... but I just really feel the need to say it. Understand what I'm saying?

[STEvil]

not a bit, actually.

That goes against everything overclocking...

whoever said it was fastest, it's not about that, it's about the tightest timings EVAR! :D

(STILL an awesome GF3 score, btw :up: )

[Firelord-OCHW]

Lowest I got was on my NF7-S with 2x 256MB XMS3200 v1.1 was 2-2-2-4 got me some nice scores on that :D

2-6-2-2 on Intel rig though!

[Sidebinder]

that is it unrealneo, that is why I posted the thread, so far it looks like some one did 3-1-1-1.5 if I read correctly. wow. :D

aight... right on..

well, have fun go tight timing then. :cool:


thanx m8... as ya know my GF3 ti200 score was done a long time ago.. I've been lazy to get back to it. I have more powerful cooling handy.. maybe I go for the higher score if I got plenty time.

[unrealneo]

love your avatar, too :stick:

good luck with future GF3 benching!

[IamAnoobieCheez]

thankx m8....

[DjTonic]

The lowest timings was 2-2-2-4. ;)
