Multi 12 might have more restricting ROMsip entries... there is some work being done on ROMsips, led by tictac, so maybe your issue will be semi-solved soon...Quote:

How high can you get stable in Prime95?

225*10 is primestable..
230*10 results in lockup after a few minutes..
For comparison sake, have you tried out the D10 bios to see how high it gets you?
Mine doesn't, a vdd between 1.6 or 2.4V makes no difference.Quote:

D10
D22
D23 subzero
With the D10 bios my cpu was recognized, so I could choose: 2500+, 3200+ etc.. by the others I could only choose: user define
I think the D23 subzero is the most stable, but I think 240 fsb is just a bit to low :/
Heads up... Ticcy fixed the CPC issue on the NF7-S bios. Search around for his fixed D24.
And then.... life was good
I'll give it a try:)
But could it just be the fact my stick is 512Mb that my max fsb 240 is?
Haldol gets up to 265 with 265Mb sticks..:confused:
I've tried the D24 .. it's less stable then the D23 subzero
D24--> 240*10 alot of errors in test 5
D23-->240*10 4errors in test 6 @: 0.2Mb, 493.8Mb and 2*256.6Mb
I got back my old corsair pc3200 xms v2.2 512Mb with CH-6 chips...
First on this board without mods it even didn't ran @ 220 fsb stable, now, 235*8 is almost memtest stable (11-2-2 2) exept 2 small error in test 5, always between 0.1mb and 0.9 mb, so i think one chip is overheating, I only don't know wich one..?
I put it in slot 2, the Twinmos BH-5 in slot 3 and now they're running @ 230*12.5, memtest stable...
I don't get in windows @230*12.5, I need to drop the multi to 12 cause I let just a bit too much gas out of my prommy (maybe disabling acpi would help):(
this gives me the following disappointing result:
jus curious whur people read the vcore from.
the unused mosfet pad by the cpu socket seems to give me a value that is bang the value I set in BIOS when at 1.65v... and within 0.2v at higher voltages under load.
If this is VCore it is a MUCH easier and safer read point than the MOSFET legs.. no risk of shorting out the pins etc.
The exact place im refering to is the largest of the 3pads... check it out ;)

Hmmz:(
230 dcddr doesn't seem to be stable afterall...
But i discovered something that may be the cause:
With the 2 512Mb dimms installed I measure unter load a vtt/vbt:vref = 1.6v while 3.3v/vdimm= 3.42v...
Could it be that the 2 512Mb dimms need to much power so the vref mosfet can't enough?
The problem is that the vref regulates the voltage from what the vdimm value in the bios is, with the 3.3v=vdimm enabled with 1 dimm vdimm is almost the same as 3.3v in bios, but with 2 dimms installed vdimm is only ~3.18v while 3.3v=~3.42v...
I don't know how this can because I didn't change anything to the board and the +3.3v is still directly connected to the vdimm...
Great read guys!
followed this thread and did the vtt mod to my board + the vdimm mod. (thanks to malves as well).
but i'm having some weird issues.
2.9 bios = 3.4 with vtt at 1.7
2.7 bios = 3.1 with vtt at 1.6
2.6 bios = 3.0 with vtt at 1.55
the vtt is following like it should (.05 down for each .1 in the bios) but the vdimm isn't going down appropriately...
any ideas why?
thanks!
Damn, a fight with FSB 250, especcialy with 10x250, is
really tiring..
As so far, I had broken 10x240 1.5h stable in P95 and
I'm still fighting, but I got problems with 250
I've tested a lot bios,D10,D22,D23 and D24, generally
tictac's
I'm not sure which bios is for me the best, I didn't tested
them exactly and I forgot what a version I had ;)
IMO D24 series is very good, I can use high vcores (1.9V
and higher) and FSB240 without big problems
Actually I'm rebuilding watercooler and working on
block's mouting, maybe I will finish it tomorrow, also
I must improve cooling mobo (NB and fans on mosfet's
radiators)
And my rig - Thorton 2000+, 2x256 one sided hynix D43, L12 modded NF-7S
okay... i can't seem to run higher than what i could pre-vtt mod...
how important is it to have the vtt @ 1/2 the vdimm?
or should i try another bios?
i've tried d10 and d23 fire rev 1 and no luck :(
If vtt isn't 1/2 of vdimm and if if much less or more your board won't even be stable @ stock speeds...
Rub87... volt mod your PSU 3.3v rail.. give it 3.6V
Is 3.6v healthy for your dimms?:p:
I'll give it a try..
not for daily use but for benching it is safe till 3.7- 3.8, just make sure you have a fan blowing at them
Bh-5 can take 3.6v daily, just make sure you have some air going across them. 3.6v is where I stop for daily use, but for benching I have gone as high as 3.9v and still gained fsb.
Now I'm running 512 CH-6 and 512 BH-5 in dcddr for daily use @ 3.3v..
@ 230fsb 11-2-2 2 , some weird thing: @ stock voltage without mod even 200 fsb 11-2-2 2 isn't stable..:rolleyes: :D
that CH6 is really holding you back I think
Nope, it does 238 fsb 11-2-2 2 in dual channel with another stick of 512mb bh-5 , when I replace that stick with a single sided bh-5 256Mb I don't get a mhz higher, the fukkn mobo is holding me back, even with only 1 stick of 256 mb bh-5 single sided 245 fsb 11-2-2 2 isn't stable... I tried every bios i think..
I suppose 1 stick bh-5 don't need more then 3.4v for doing 245fsb single channel..? does it?
so replacing the CH6 with BH5 does gain you 8MHz FSB? Seems like the CH6 is holding you back...Quote:

3.4v should get BH5 to and beyond 250FSB for sure... with 1x512MB stick I am stable at 250 2-2-2-11 @ 3.2v and can bench at 255 2-2-2-11. But with 2x512 I am only 100% stable at 232 2-2-2-11... although I can run 3DMark '01 and '03 up to 242 2-2-2-11. All this is with CPC ON and BIOS D10.... the best D24 version limited me to 229FSB for Prime & 3DMark.Quote:

Try running a single BH5 stick in Dimm3 with 3.4v and see how high you get. Disable "APIC" and "Enhance PCI Performance" too ;)
Good luck dude
Non U'r getting it wrong, with:
1 stick 512mb XMS pc3200 rev 2.2 with CH-6
1 stick 512mc Twinmos BH-5
together in DCDDR I can run super pi up to 238 fsb 11-2-2 2
But when I replace the stick XMS with a small 256mb twinmos bh-5 stick so I'm running
1 stick 256mb Twinmos BH-5
1 stick 512mb Twinmos BH-5
In DCDDR I don't gain a single mhz:confused: so I tihnk the CH-6 is capable of more, when I only use the small 256 mb BH-5 stick even 245Mhz isn't memtest stable:help:
