Should have posted this into this section.
A little ways back, I bought an NF7-S 2.0, and an Athlon Mobile 2500+ with a Prommie MachII. Loaded everything, and the most stable FSB I can hit is 197, even though I've read this mobo should normally hit 220+.
The memory I'm using is OCZ Gold 4000 (500MHz). Updated the BIOS (three different versions - no diff- now on an 'uber BIOS'), ran through every setting in the BIOS and went through various combinations to no avail (currently @197*14)
RAS/CAS settings 7/3/3/2.5,
VDIMM setting at was @ 2.8v as rated,
CPU Interface On,
CPU Disconnect Off,
FSB/AGP Spread Spectrums are Off,
Raised and lowered the vcore which is
now at 1.85Also played with various multipliers to no avail (I've read there tends to be a 'sweet spot' on most chips and is usually the 'stock' multiplier.
I've also tested the memory a friends unmodded NF7-S 2.0 and it hit 225 on that, stable running for 8 hours with SETI and Prime95.
Not sure what the bottleneck is, and considering doing a volt mod on the board. The symptom when it fails (at FSB higher than 197 is the dreaded reboot (i.e. random reboots). BUT, if the CPU simply refuses to go any higher, I'm guessing a vmod won't do any good and I be hosed.
How do I figure out where the bottleneck is? Could be the mobo or the CPU, and if it's the CPU, I'm screwed. If I need to buy another mobo or CPU, may as well just get a Northwood or Prescott and an Asus P4P800 etc.
Any pointers? Help.
Thanks
Joe

jeez, i can hit 204fsb with my retail 2500+ nonmobile with the stock hs/f on my nf7s with pc3200 mushkin basic green and be stable
also i always keep my vcore(if i oc) at 1.675
try this
set vcore to 1.675, multiplier to 11, and fsb to 200 and see if that doesnt work
if it does then you can go from therei think your vcore is too high as well as your multiplier

Responses to the above (Thanks for the quick replies!):
Actually it's a Mobile 2600+, not 2500+ - didn't put that down right. Rated speed is at 2GHz (133*15), rated FSB at 266 (133*2). Current FSB is at 394(197*2) - but I've read all over the place of people running 220+ FSBs w/it.
1. The 'regular BIOS' version I was running was 1.21.
2. You can run memory faster than PC3700 if the FSB/mobo will handle it. The memory is just another component (and possibly bottleneck) in the system - the reason I got OCZ 500 is so I knew it wouldn't be the limiting factor.
3. Believe I've tried running with an 11 and 15 multi to no avail - will try again. However, my goal is to get into the 220's on the FSB - won't get anywhere near that on a multi of 15 (unless I use some liquid nitrogen and try and hit 3GHz+ with this chip). So, think I need to keep the multi down a bit. Trying to hit at least 2.6GHz w/a 220+ FSB.

I think you got it slightly skewhiff somewhere bud.
Leave the multi at 10
Try fsb of 190
If ok then increase fsb by 5mhz increments at a time untill not okWhen you find the stable setting,back off a touch.
Then try increasing the multi.
Bios 10 & 24 are supposed to be the better ones
Also what psu you got?

Max. CPU speed is the combination of FSB and Multi. You cannot have both worlds; lower your multi to 12 and increase FSB to 220. Adj FSB upward to find the max speed.
I too have the same setup (AXP-M 2600+) @ 200 x 12.5 with 1.7 Volt. Could get up to 2700Mhz, but don't need it.

Upgraded the BIOS to 1.24.
Not bad - you on air? Wondering if the electricity the Prommie sucks up is even worth it (and that's why the note of possibly buying a P4 above - run SETI but my electric bill was killing me running it 24/7 so I started shuttin it down 1/2 the day). My bill went up $25/month running the Prommie.
Tested 210* 10 - stable.
Then 215*10 (and upped the vcore a bit to 1.55) - no go.
Then 215*10 (1.6v) - no go.ANYHOW - now at 210*13 and stable (so far).
Think I'll let it be at that.
Thanks for all the help - really appreciate it. I'm an OC addict and hard to quit pushing it.

lazyman likes air and dislikes noise.
Get lazy and read some articles...

Howdy Skip,
I like W/C also, but don't tell me it's all very quiet. They are not that quiet; a 92mm radiator fan or 120 mm tuning 1500 to 2000 rpm with a radiator behind it can't be quiet.The radiator and pump sitting inside the case can't be that efficient. External ones are better but don't tell me you would be able to maintain several systems with the same "care" - one for each of your children,and of course your wife or girl friends. If they don't have W/C, you are only partially W/C.;)

Hi,
Just a comment to backup watercooling systems..LoL..Although i agree that some W/C systems are not that good.... You generally get what you pay for, But my own W/C system being a
"waterchill" system with and 240x120 Radiator that holds 2x120 silent fans for which i may add is fitted completely outside my case.The pump is fitted inside the case and i have to say you can hardly hear the pump or the Radiator fans over my 7 case fans for which are very quiet..!!
In my own experience W/C are more quiet than air...

Sid,
I can read enough of that review to see not much has changed with the CV...it just works. I kinda like the real world testing approach.
My problem with a w/c setup big enough to do the job is that it blocks necessary airflow thru the case and you get a cool cpu while you watch the rest of the rig cook in it's own heat.
External w/c solves the pump and radiator blocking airflow problem but moving the thing around gets to be a real hassle. It also seems that two kinds of w/c exist...those that leak and those that are about to leak.
To each their own but if I have to use fans to cool my case, motherboard, mosfets, and so forth with air, I'll continue to cool the cpu, gpu and other chipsets with that same air.

Not all NF7-S V2 boards let you go up to 220, and almost all boards have the 10x, 10.5x problem with CPU interface enabled. Try 11x to see if you can pass 215FSB. If you do, raise multi to 12 and your Vcore should be around 1.8V. I RMAed 3 boards before I found one which could go up to 220.
