Quantum Force MARS P35 CPU PLL, NB GTL, FSB Swing Mods

[LardArse]

CPU PLL VMOD

Just near Southbridge if you need more than 1.95v PLL:



You can use pencil or a 10K ohms VR. For 10K ohms VR set at 10k ohms first tune down for more voltage.


MCH GTLRef AKA FSB VRef & VFSB Swing




Beside chipset. Set at Max resistance and tune down to increase voltage. Both voltages are derived from CPU VTT - Default = MCH GTLRef ~ 0.66x VTT, VFSB Swing ~ 0.25x VTT.

How much effect was PLL worth on 45nm frozen?

Fredyama said he hada bout 5+MHz FSB gain, updated with NB GTL and FSB Swing mods

Thanks for the post

What is FSB Swing Mod for?

Thanks so much for the voltage mods

5MHz gain was with my second best E6850; have seen its best one about 15MHz gain @2.44 -- 2.48V on air.
Not sure about 45nm frozen though

Host compensation reference voltage, read more about it:

P35 and X38 similar.

Thanks again - got some reading to do now

Hi,

i have the board now but the vcore droop is 0.024v with a dualcore, someone know
a droop mod for this board?

Thanks
Chris

Droop mod tune down resistance for lesser droop

Is there a pencil mod for the vdrop?

I'm testing my E8400 on this MARS mobo and it is amazing, one weird thing to me is that the NB volts afect a lot on the CPU FSB. I got 25MHz more by increasing the NB volts. This helped a lot on max MHz clocks.







I'm using bios G29, the half multis get a wrong CPU MHz in the BIOS. Is there any other improoved bios for this wolfdales?

P.D. my chipset fan was imposible to attach the right way so i had to attach it on the other side, i spent like 30 mins trying on the correct side.
P.D. 2 i gotta test with 2 cores enabled now
P.D. 3 when can we get MARS DDR3?

Super board Shamino! Doing the vdropp mod now.. hoping for 5.5Ghz benchable.

yes, it need much NB VCore

500FSB = ~1.45v
555FSB = ~1.90v



on P35-DQ6 did it without problems 570FSB....

[saaya]

nice!
thanks for posting the mods man!

pll voltage to 1.9v gives me a 15mhz fsb boost on my 6750 on air, more doesnt help, tried up to 2.2v...

i heard 2.4v is too high for 24/7 and one guy damages his cpu with this.
so be carefull with too high pll voltages

[HDCHOPPER]

ahhhh just found this thanks sham !!

metro.cl is your E8400 chip still ok running that volts ?

want to try high volts ,,, and your chip has been running a while now and was wondering about degradtion
