Am I Lucky Or Is Value Select Just Good?

Hey i got a 1 gb kit of crosair value select ram and i can get my ram up to 240fsb with HTT@4x 1:1 ratio and timmings of 2.5-3-3-7. is that just luck or just good ram?

Try running Prime 95 for at least 8hr, then some 3Dmark benchies & see if your lucky.
Run a mem test too.
If your system isnt stable ya got nothin.

What matters most on a AMD 64 is the Max MHz, mem speed not so important.
Try a divider & Crank it up some more

A stable 2640Mhz, is Nice

 

well prime failed in a half hour@240, but it was stable @235 for 8 hours. 3d mark 05 ran stable @235 also but not @ 240(failed the cpu tests). but im still happy with that.

 

running your HTT at X4 is giving you a HTT speed of 960mhz underclocking your HTT,since your HTT is your memory bandwidth any gain you may think your getting will be lost due toHTT bottlenecking,try running Sandra memory bandwidth benchmark as it is now and then set your HTT multi to X5 and overclock your HTT until it tops out then run the benchmarks again see if you can beat my MSI neo 2 memory bandwidth OC'd to 260 fsb HTT X4 =1040HTT ram at 4\5= 208mhz 1gb corsair twin x dual channel

 

ok here is mine. FSB @ 235 HTT @ 5x 1:1 ratio...i dont like to use mem dividers...plus i dont have dividers in my bios.

Is that your HTT at 235 x 5 = 1175? if so thats an awsome HTT overclock,are you using a single stick,that would explain why you only have slightly higher ram bandwidth than mine as I'm running in dual channel EDIT again just read your running in dual channel sorry mate I'll have to pay more attention

you will have a ram devided it wont be labbelled as such though in your ram options there should be an option ddr 400 or ddr 333 setting it to ddr333 acts as the 4\5 devider,if you need to raise your fsb higher this devider is essential for getting getting your max cpu overclock

EDIT sorry just read your HTT is at 1175 in your sandra pic

 

okay i have a question. Is it okay to overclock my HTT bus from 1000 to 1175 if it runs stable?

It depends on board stability,I'm suprised you overlclocked it that high without raising HTT volts,make sure you have plenty of airflow through the case to keep all those motherboard components cool,my msi neo 2 will only take a 50mhz HTT overclclock before it starts failing prime,to workout your highest HTT overlcock drop your cpu and ram devider down a few notches so your after raising your fsb you know only your HTT can max out once your overclock fails prime knock your fsb down one MHZ at a time and run prime after each,as a rule once I have the max stable overclock I knock it down 5 more mhz to be on the safe side, depending how much of a safety blanket you want,once you have this number its just case of working out the best combination of cpu multi,ram devider and HTT multi

If you can run prime95 overnight it should be completely stable

 

with Valueselect RAM, it's all luck of the draw. Some people (like you) get great RAM that will overclock till the cow jumps over the spoon. Others get RAM (value select) that wont' go 1 Mhz over spec.

 

This statement is wrong,increasing HTT has obvious real world performance gains as your memory bandwidth cant be increased without opening the HTT up,if you run your memory higher than your HTT the information will be bottlenecked by the HTT,leaving the HTT 1000 is like giving the cars a 16 lane highway in the memory then cramming then all into the HTT 10 lane highway

try it,test your memory bandwidth at 1\1 then raise your fsb and memory speed and knock your HTT multi down to X4 and raise the FSB until the HTT is back at 1000mhz you will see an obvious drop off in memroy bandwisth at 1000mhz,also try running 3dmark 2001 in both scenarios to see the effect of HTT speed

 

MY statement is Correct
Run your's how you like makes no difference to me.

The memory does NOT transfer thru or over that bus so it has no bearing on Sandra memory bandwidth testing either. The memory talks directly to the cpu as the memory controller is there in the cpu.


At Hailscott, ya better run some stability test's

 

I'm gonna have to find some HTT overclocking examples,if you can find some that show theres no reason to overclock the HTT,that would shut me up lol

 

Looks like I'm wrong ASUS I apologize,I bet this was the article you got your lane example from,well you learn something every day

That link is like the Holy Grail of A64 OCing.


No harm Rikky

I like the lane example, Too bad I didn't come up with

I'll see ya
