Crew Strunkenbold Posted February 4, 2014 Crew Posted February 4, 2014 Why not using win7 64bit or is this winxp 64bit? Quote
Mat_Agnesi Posted February 4, 2014 Posted February 4, 2014 Thanks to everyone / Grazie a tutti Strunkenbold: This is XP 32bit. Seven 64bit does not seems to score better. May the XP 64bit score better than the 32 bit ? Quote
Crew Strunkenbold Posted February 5, 2014 Crew Posted February 5, 2014 From what I saw, for me win7 64bit with 64bit JRE was always a little bit faster. But never tested on Penryns so situation might differ. Quote
wytiwx Posted February 19, 2014 Posted February 19, 2014 Chipset limited I think, 3:4 ratio is MCH 200 strap, top trap for PM965, you need a PM45 mobo, by which you can get 266 strap and so higher Freq. Quote
Mat_Agnesi Posted February 20, 2014 Posted February 20, 2014 I have overvolted the PM965, and at this frequency this rig has passed the Wprime 1024, so is it very stable. I think it can go higher, but unfortunately the software " SetFSB " can't set more than 315MHz FSB. P.S. I notice also better efficiency for PM45/GM45 chipset, more point for same MHz Quote
NoMS Posted February 20, 2014 Posted February 20, 2014 ...I think it can go higher, but unfortunately the software " SetFSB " can't set more than 315MHz FSB. Did u has tried to change these parameters "PLL N"/"PLL M"? Quote
Mat_Agnesi Posted February 20, 2014 Posted February 20, 2014 Nope, I change two different version of the software, but never touching this parameter. I simply raised the clock. I can set all the frequency from 200MHz to 315MHz FSB, but, if I set for example 320MHz, the software seems to accept the command, but the real FSB frequency still remain fixed to 315MHz. Even If I set 330MHz, the FSB freq. still remain 315MHz Do you think that parameter can unlock the situation ? Quote
NoMS Posted February 21, 2014 Posted February 21, 2014 (edited) Nope, I change two different version of the software, but never touching this parameter.I simply raised the clock.

These parameters can raise the limit of fsb adjust, i mean, if the max u can set is 315MHz on the slider, it will raise this. If the problem isn't the max limit of fsb slider, I think this will not fix. Edited February 21, 2014 by NoMS Quote
Mat_Agnesi Posted February 21, 2014 Posted February 21, 2014 The FSB slider can go up to 380MHz, but the FSB will lock up at 315mhz. This is a strange problem ! may be possible that the clock generator has reached it's limit ?? Quote

Maybe it can clarify something about this mysterious fsbwall. Quote
ludek Posted February 22, 2014 Posted February 22, 2014 Hi! Is this a RTM875T - 606 clock generator? What is on 3rd photo? The fourth foto I guess is the way to vCore vmod, am I right? How big is vDroop on this notebook motherboard? Nice score!! Quote
Mat_Agnesi Posted February 23, 2014 Posted February 23, 2014 Hi! yes, the Clock GEN is RTM875T-606. The 3rd pictures is a detail of the VID Vmod for the CPU (The scratched point, is where I have soldered the wire). The 4th pictures, is the Chipset Vmod. I haven't checked the vDroop.. But I think it doesn't have so much vdroop. That mainboard can use a T7700 CORE duo CPU, witch require so much power if compared to a single core Celeron 925 45nm, even if overclocked. Quote
Mat_Agnesi Posted February 23, 2014 Posted February 23, 2014 Unfortunately I can't find any detailed Datasheet for the RTM875T-606 If anyone can find it, please post here. thanks Quote
ludek Posted February 23, 2014 Posted February 23, 2014 How are you changing FSB value? I found this, also unlocked a logical input on 4th pin "TME" from 1 to 0. Setfsb - > import PLL and it is working. Now i'm going to do some vmods and check this 315 MHz wall. Maybe I can be able to get this datasheet, but it'll be hard, but I'll try Quote
Mat_Agnesi Posted February 24, 2014 Posted February 24, 2014 Yes, I've used Set FSB to change the FSB from Windows! I think this is the only way to overclock a notebook without any option in the bios. With other CPU, I've got a lower FSB limit. For example with an older 65nm Core 2 DUO model the fsb won't go over 265. Quote
wytiwx Posted February 24, 2014 Posted February 24, 2014 To Mat_Agnesi: You can try FSB 800 to 1066 BSEL pinmod, if it worked, may help to get 315MHz+ Quote
Mat_Agnesi Posted February 25, 2014 Posted February 25, 2014 Yes, that's should be tryed. If the system start up directly at 266FSB, it may not lock at 315. However: with the BSEL mod the CPU force the system to start up at 1066 FSB, but the PM965 only support 800FSB, what does happen ? It may be an interesting thing to try. Quote
wytiwx Posted February 25, 2014 Posted February 25, 2014 DELL Latitude D630 is PM965 too, can boot at FSB 1066 by mobo PLL pinmod. You also can see this page: http://forum.notebookreview.com/hardware-components-aftermarket-upgrades/393027-pll-pinmod-overclocking-methods-examples.html For Mobile Celeron 900 (925) chip, firstly can do Socket BSEL pinmod by copper wire, that is a safe way. If it not worked, then have to do mobo PLL pinmod, a harder and more dangerous way. Meantime watch your Memory clock, may lead to crash if too high. Quote
Mat_Agnesi Posted February 27, 2014 Posted February 27, 2014 This is an interesting experiment to do. also because my DDR2 notebook RAM overclock very well, can raise near 500MHz with CAS 5-7-7 or 6-7-6 Quote
ludek Posted March 23, 2014 Posted March 23, 2014 I'm having the same problem: 315 wall. No way to pass through this. I did 166->200 FSB mod, it is working (On T5750). Tried to do 200->266 FSB mod, but it doesn't work. Probably a bios limitation. vNB ~1.32-1.35V allows to work stable at 315 MHz. No way to set memory divider, but SPD Tool is very helpfull. Any ideas? Maybe I will try modify logic imputs in clockgenerator. Quote
Mat_Agnesi Posted March 24, 2014 Posted March 24, 2014 Good work. So even the BSEL Mod does not work. We have to discover if this wall is simply caused by the Overclocking software (Witch cannot set more on that platform) or is an hardware limitation. If you attempt to force the FSB frequency via Hardware mod on logic inputs clockgenerator, we will discover this ! Quote
