nForce2 Higher tRAS yields better performance and higher overclocks?
 
Quote:

I jacked my tRAS up to 11 and checked my memory performance and my scores were noticeably higher. One side benefit to this modification is that my memory could be overclocked even higher with no loss of data or stability. So I did up my FSB to 175MHz (cut me a break, I only have PC2700 HyperX) and dropped my multiplier to 12 giving me 2.1GHz, otherwise known as Barton 3000+. This is all at default voltages, too.
Actual post here

Im gonna try this and see if I get any effect. If anyone else tries this post the results and all to compare.

Hi ,

I`d heard of this before, and as trying to OC today decided to see what figures I get using this TRas.

Memory @ 7,4,4, Cas 2.0 : 3033/2811
Memory @11,4,4 Cas 2.0 : 3055/2828

3D Mark 2003 @ TRas 7 = 1818
3D Mark 2003 @ TRas 11 = 1824

Seems to work for me ..but not staggering . Still every little counts :)

Hi ,

Here`s my system specs ..I`m very pleased with the RAM speeds ! I bought generic Winbond CH-5 chips from Ebay for $107 incl. postage (£66) , stuck some thermaltake heat spreaders on them ,and now have them running at 432 mhz @ 10 ,3,3,3 Cas 2.0 with absolute stability !

i have winbond memory too, can run them at 460ddr and at 6-2-2-2.....changing to 11-2-2-2 gave me no change in performance.

Hi ,

460 DDR ie 2x230 ?? Very impressive , I presume these are PC 3200 chips ? Do u have active cooling on them ,and what is your VDimm ?

Thanks,

Gerry :p

Gokou 23rd July, 2003 08:23 PM

no active cooling - cos its a scam and ddr memory doesnt produce any heat :}

vdimm is roughtly 3.15v

Hmm !

Hi ,

no heat ? nope thats not true I`m afraid ..put your hand on your RAM chips after a heavy session and yes they do get hot !

3.15 Volts ? My mobo doesnt have any settings above 2.9v , and its an overclockers one . What mobo are u using ?

Just curious , those figures are quite amazing ..can u post a Wcpuid pic of them ?

Thanks ,

Gerry

yeah 2 seconds, just gotta download it - formatted and forgot i didnt have it :{

oh and im using an abit nf7-s..... its had the chipset and dimms voltmodded.

oh and they are in dual channel slots and bios confirms this - dunno why cpu-z says single :/

Hi ,

Thats a very impressive overclock u got there ! :thumbsup:

I`m having real problems pushing past 215 FSB and its not RAM related ..I`m waiting for the gurus on here to make some suggestions about it ..another site thinks I`ve reached my processor max speed but I find that hard to believe :(

I might try pushing some voltages after seeing your overclock, and see if I can crank things a bit further .

Prime 95 stable too ! Hats off , my friend :D
