1000+Mhz HTT...and still stable. - Page 3

post #21 of 36
It's a similar purpose to FSB except it doesn't actually connect the memory... I still don't understand why it helps the memory OC, but it does.

I currently run 240mhz and 1202mhz HT (2404mhz) and its stable. The increased HT will increase your memory bandwidth, by alot, and intern increase performance. Stock my bandwidth is about 4gb/s. Thats at 1000mhz, and at 1202mhz i get 6gb/s. Thats a hefty increase i think.

But mine isnt stable above that. HT doesnt overclock very well.

HT works by not using an FSB, it connects to the memory faster by having an onchip memory controller rather then having to go through an external memory controller on the motherboard as Intel CPUs have to.

I run an FSB of 255 & HT at 1276; If I lower the HT speed then it all gets horribly unstable.

False, the HT link doesn't have anything to do with memory, which is why I can't figure out why it helps.

In theory, the Athlon 64 can communicate with the memory and with the other circuits of the computer at the same time, something impossible in the other processors, for there is only one communication way.

i guess i understand ...but what do you think if my 2600+ sempy at 1.6Ghz has 800HT and at 2Ghz has 1000HT...is that ok? i must say it's very stable...

Note: Disable anything with "Spectrum" when OCing... also disable Cool N Quiet.
The HT...
Default 4x200MHz for 800 ... even though it's then x2 for a true 1600, no one refers to it so just keep 800 in mind. (note, that is with 754 MBs, 939 utilize a 1000 max)
Many 754 MBs can easly excede 800 and keep stability but there is a point where stability becomes an issue, so...
When you increase the CPUs OC the HT increases.
Example: CPU OC @ 250MHz, with the HT multiplyer @ 4 you have a total HT of 1000 which may cause instability. Drop the HT to 3x for a 750 HT to retain stability.
Generally the 754s should do up to about a 900 HT stable but all MBs vary.

After reading that, i dont see how what i said was false. Since that just says what i said, only in more detail.

Read your quote, it explains how it effects the memory, and why increasing the HT would in theory increase memory bandwidth and performance.....

To make it more obvious, go into your bios and reduce HT multi to x1 and see what happens to your memory bandwidth, it should drop dramatically, and your entire system would be VERY slow.

Look at the image...like i'm on a 754mb...and at this point it's perfect stable...even if i go to 2100Mhz it's still stable...but i can make it 800 at 2Ghz...my question is how will it affect my performance??

Hey Subtle Nice OC on that 3800, and at relatively low voltage too. I've ran my DFI board at over 1000 and had it perfectly stable with no prob.

Can you get 3ghz. stable with your chip?

HTT has NOTHING to do with the memory or memory bandwidth. HTT connects the CPU with the chipset, that's it. Yet you're trying to say that it helps by increasing the memory bandwidth.
