So what is the cpu fsb? I understand the the cpu core is the one we crank for the cpu but what about the cpu fsb?
no, it's the other way around.
SPP is the north bridge
MCP is the south bridge
just remeber.... S=system M=media
The reason why I ask all this is for better understanding... Currently I just do what all you do and it works... crank this up and then that... and bench check it with prime95. I want to understand a little bit more about some of these "things" we are giving volts too.
Also if anyone is interested in enlightening me... why crank pci-3 mhz to 125? and why crank spp mcp ref clock to 250mhz?
cool... thanks... makes a bit more sense as to what that is... what about the rest?Quote:

CPU FSB is the CPU VTT, It says it in the Details in the BIOS. Not sure what it does but you have to balance it with the Vcore
I havent touched the SPP MCP ref Clock yet, im trying to get this Vcore lower, it just failed at 1.325 (1.26-1.27 underload) so im back to 1.350 (1.30 on load) So this is stable pretty much. I have a good chip, 1.1125 VID so this baby can do it. I'd leave those SPP MCP ref clocks alone, and the PCI-3 I havent touched either so meh, I dont really think it'll do much in terms of gaming performance, the Ref clock from what i've read gives you a few more points in benchmarks which doesnt mean much unless your a hardcore benchmarker trying to go for records and stuff.
i had my e8400 @ 4.32ghz @1.38v(actual, set 1.4v in bios) on my pencil modded 780i(fixed vdroop). my q6600 ran at 3.6ghz @ 1.5v and 3.9ghz @ 1.56v
the NB was set to 1.5v, ram was set to 2.3v(your's may be lower, and probably should be). everything else is set to auto.
Im scared to do the Vdroop mod because this is a brand spankin new board. How were the temps? Im using the Zalman 9700LED which is a great cooler. Underload atm im at 51C with Prime and OCCT going
What do you estimate for 4GHz Flat? (1780 QDR)
This is just my opinion. Look at this image of the 780i chipset...
Attachment 72742
CPU Core: CPU
CPU FSB: I'd bet this controls the signal between the CPU and SPP.
Memory: Memory
nForce SPP: The voltage that controls the SPP.
nForce MCP: The voltage that controls the MCP.
HT nForce SPP <-> MCP: The voltage that controls the signal between the SPP and MPP.
Do we have any descenting opinions?
Makes sense to me... I'll give it a shot... recently I've tried to boot at 2000 or 4.5ghz and it bsod' about 30 seconds into windows... what up with that? I have vista 64bit.
my 780i is down again...
cant recover from a failed oc, all i get on boot up is "ff" no post...put in for rma this is now my second time... :(
sorry to hear that, I got one of the 2 i had go down fixed as it seemed to be a bad video card, the other I just received back from rma. so far so good.
Hughy, try 1800 QDR and link and sync the ram to make sure your mobo and chip can do it. Right now im pretty pleased at 3.83 with 1.3(1.35 in Bios) on Vcore and 1088 on the memory with everything but Vcore and Memory voltage on automatic, This board can really scale well with an OC im really happy with it :up:
I'm not familiar with the vdroop mod or how to do it... please explain!Quote:

I think it's 1.76 actual in CPU-z... is this on the right track. I really havent primed for long periods just 1 hour 17 minutes.Quote:

yeah, battery pull didnt do it...and what a pain to pull out 3 cards to get to the battery...
evga ok'ed my rma, so with luck i might get my replacement tomorrow, but i think when i get it i will just run a single card and put the other cards in som othe rigs...
Do SLi (2). I honestly dont think the Tri-SLi is worth it, Ebay the other card you have left and call it a day
This board runs great with 2 8800GTS so i'd say 2 cards, Tri-SLi is too new if you ask me
I'm seriously looking at getting one of these since I want to get either a 8800GT or 9600GT SLI setup. I'm really worried about getting a really hot running NB however, what do you guys think are the chances of that happening? Also any issues with this board at stock speed with 2x2Gb PC8000 memory? Sorry for so many questions.
Do the 8800GT, 9600 is for the midrange, 8800GT, i would say is closer to high-end then any of them. My NB doesnt get very hot at all to be honest, especially if your staying at stock. I'd say go for it man, these boards rock :up:
Thanks, reason was I wasn't sure what the price difference would be here in New Zealand but I just checked my e-mail and it turns out the difference is only NZ$50 which isn't enough to justify 9600GT. May I ask exactly how hot at stock volts under load please?
Thanks
My SPP is idling at 51c, but its not at stock, i have it at 1.55
yeah, i agree the tri-sli is way overkill and not worth it at all.
Tri-SLi can be beneficial in the future, but atm i'd say no, No games need 3 Ultra's (This excludes Crysis because its, Well... Crysis) even at 2560x2480 or w.e that resolution is.
Yeah... mine is running 2x2gb very stable with tight timings. I couldnt be more happier with the memory I purchased.Quote:

i stilll have the new rma'ed board in unopened box from newegg
its probly worth more if i sell it unopened lol;)
