I thought the chipset voltage was the htt voltage?

Nope the LDT Bus needs juice to.

LDT voltage control set to 1.3 volts and the chip set voltage control set to 1.7 volts. that might help with stability issues.

Heres the best i can do, not sure why either, i rekon its the mobo dont like anything above 310 htt but i might be wrong,

Link
any ideas how i might get this any higher?

lol thats a crazy big bmp file dude, 5mb+!!

300fsb+ is surly pretty good going with any asus board?!

cutchy2k · 19 Dec 2005 at 02:23

heh yeah thats just me being lazy, plus i aint hosting it uni is

Do you think a new mobo might help with the overclockin?
i got an A8n sli-d at the moment but the DFi and the Abit fatality look good.

what about vcore? is 1.5 ok on air i dont know much about that.
i know my memory should be able to handle higher FSB and i rekon CPU has some more power to kick out just annoying im like 5% off FX-57 scores in sandra etc.. :S

Hesky82 · 19 Dec 2005 at 03:36

if your coolings up to it maybe you can run a little extra vcore, but unless your under phase there isnt much more to be had really. keep an eye on temps, 60s a good limit.

If you think its worth buying a new mb just to get that extra 5% i say go for it

nice one clint! just wondering, which rev ultra-d board do you have?

Hmm, I can't tell from here...does a P/N NF4U91-134M help?

Must be a pretty good batch though, given that 400mzh HTT was reached pretty easy.

lol nope thats the part number, its the next set of numbers/letters next to that on the pci-e slot. usually a**

Could you tell me what each of these are for. Which one is the LDT voltage?

the ldt voltage adjustment is seldom to dfi nf4 Boards (lanparty, infinity) afaik, I've not come across another motherboard that allows seperate adjustment of the ldt bus.
The hyper transport bus (aka ldt bus) is a packet-based data transfer protocol, with each packet consisting of a set of 32-bit instuctions, I've noticed if your voltage is to low you may still get a "stable system" but your 3dmark scores maybe really poor! this is because some instuction packets are incorrect and there for ignored, systems get slower but do NOT crash. (hence why you see a lot of people complaining about low overclocking scores)

with boards that dont have an ldt voltage adjustment keep an eye on your bus speed, try not to exceed 1000mhz.

Yup, found it.. AD0 (a)(d)(zero)

Got my 146 today. Shame im not at home yet to find out what stepping I have :\ not sure why im so intrested as need to get a mobo, better ram to clock it lol and as I have no money at the moment its gonna take a while to do lol

Maxx1984 · 19 Dec 2005 at 21:40

Its a CACJE/CABJE (havent got the box on me atm) hope its good enough for clocking..

Hesky82 · 20 Dec 2005 at 23:56

Hi guys, finally got around to overclocking my opty today, managed to get a stable 2.95Ghz @ 1.36volts

it will run 3ghz at stock volts but will only pass 1m pi, no go with occt etc.
tomorrow will play about with a little extra vcore and see where we max out then

zalman cooler seems to be doing a good job so far!

sepulchre · 21 Dec 2005 at 00:04

Hesky, Nice overlcock... looking forward to doing the same on xmas day

Can you tell me what app you have running that produces the lower right display? Cheers

Thanks for the link, but how much of a noob do I look

/ in my defense the interface on MBM has changed some what since i used it a few years ago.

Hah, and I though mine was nice and cool...yours is very nice indeed.

May I ask what you have there, is it FPBW ?

Rob43 · 21 Dec 2005 at 13:52

310x10 here.Temps 31C Idle 46C Load :eek:

same as yours clint, FPAW I'm trying to get a prime stable 3.2ghz at 1.4v

I sware it can do it!

edit: the batch code of the cpu is 50459

Sumanji · 21 Dec 2005 at 16:11

Hesky82, do you mind posting your GenieBIOS memory settings please? Using A64Tweaker or something.

Cheers,

Suman

Hesky82 · 21 Dec 2005 at 16:36

Suman, I dont use a64tweaker, but this is a copy of my bios. I tweaked ram timings so I could run as low vdimm as possible.
