RAM timings or High CPU speed?

[OrangeParktech]

I found that relaxing my ram timings gave me a little bit extra on my overclock, and now my question is this. which one of these 2 is faster? Both are with RAM 1:1 with FSB.

250x10 4xHTT 1.47 Vcore
RAM at 2.5-4-4-7

or

260x10 4xHTT 1.50 Vcore
RAM at 3-4-4-10


Any help would be appreciatted, and any other RAM timings that are better would be great too, 3-4-4-10 is just what i happened to change it to. I imagine the 3 is the number helping me clock higher.


I'd love to run at 2.6GHz, as it was my goal when i bought the CPU, but if it turns out i am better off with the lower RAM timings, i will gladly go back down to 2.5.

I'd stick with 2.6, ram timings don't have a huge affect on performance with the A64's.

3200+ to 2.6ghz, lookin nice!

Yeah im pretty excited, as this was my ultimate goal when i bought the CPU. I actually was able to tighten the RAM to 3-4-4-7 and it benches just fine. Anything lower, like 3-3-3-7, and it wont even post.

So the final overclock is 2.6GHz.

260x10 4xHTT @ 1.47 Vcore
260FSB RAM @ 2.85v 3-4-4-7

Nothing, including 1.65Vcore or divider for RAM would go even 5MHz higher, this is the true limit of this CPU. This is on Air with the stock Heatsink, but with Ceramique instead of the AMD pad.

Idle 34c
Load 46c

Im happy with it.

very nice, im in the process of getting my 3000+ to 2.6GHz. running prime95 right now . very low load temps, mine are always 50C+. my idle is around 34C also. i sorta wish i got the 3200+ instead of the 3000+, cuz i could run with a higher HTT multi. in order for me to run at 2.6GHz, my htt is at 290 . this means a 3x multi lol
anyway, nj and wish me luck

 

[OrangeParktech]

Good luck with it. My load temps were around 55c or so until i put the ceramique on and burned it in, now i only get 2c better idle, but a whopping 9c better under load. I was thinking of getting a better cooler, but since my temps are in good range, and my CPU wont go any faster anyway, i figured i'd wait awhile.

Next investment for me is a new video card to complete my system. Im either going 6800GT, or maybe even a new Nforce4 Motherboard and a PCIe card.....either way, i have about a month to think about it.

zakee00 my understanding is the differnce with 3x vs 4x htt is minmal if you goto extremesystems..someone benched at different htt and found virtually no difference....I can not find the thread but is was excellent...

also seems with the A64 Zebo showed high end memory is overrated as well

is your 3000+ prime 95 stable?? if so that is one awesome o/c

OrangeParktech is your cpu prime95 stable..I can run games and winxp on mine at 2600 but it craps out in prime95 after 5-30min

 

[OrangeParktech]

Prime stable...

All im worried about is my Ram timings. Everyone says the ram timings dont mean anything, and that the extra overclock is better, but toms hardware has an article that says the lower CAS RAM is best for A64's...

 

[Mrvile]

lol what is Tom's talking about? A64 are about the least dependent on timings...

 

[OrangeParktech]

Im glad you said that.

This puppy is flyin at 2.6GHz. Memory bandwidth in Sandra shows just over 7000, SuperPI 1m is 33s, and prime95 ran with 0 errors for about 3 hours or so.

I cant say i have noticed a difference between 2.5 and 2.6, because the thing was flying before hand anyway....lol...but it sure looks nice seeing FX-55 speeds when i check

Thanks for the help.

Don't say that!! It's not an FX55!!!!!

 

[zakee00]

it basicly is, the extra cache makes barely any diff. and i cant seem to get past 2.43ghz (which is totally rock solid, prime 8hrs memtest 4000%). im going to try once more tonight, then i think ill leave it alone.

 

[Mrvile]

What I meant to say was, It's actually better than one. The higher FSB combined with the 90nm process makes up and over for its lower cache.

 

[OrangeParktech]

Yeah, 260x10 is much better than 200x13, and the 1m L2 cache just cant make up for that kind of difference in system speed.

Now sure the FX55 can be overclocked to be faster than my 3200, but the entire art of overclocking is to save money and get better results than something far more expensive, thus feeling like you really got yourself a good deal. At least thats the way i see it, other than the fact that its fun to tinker as well...lol.

3200 Winchester @ 2.6GHz = 220.00
FX55 @ 2.6GHz = 880.00

Difference of 660.00, and the 220.00 overclocked is faster than the 880.00 at stock.

Thats what overclocking is all about
