I've used this S754 setup twice, first time 2018 Team Cup, results.
3000+ Venus, FSB 289, RAM DDR 526
3200+ Venus, 284, 522
3400+ Venus, 263, 526
This session
3000+ Clawhammer, FSB 240, RAM DDR 480
3100+ Clawhammer, 240, 480, (9x Multi, SS looks like Knop's 2900+ SS)
3200+ NewCastle, 240, 480
3400+ NewCastle, 237, 474, (This one is probably capped)
Things that are different
W7 to XP
7800 GT to 6600 GT & card drivers due to OS difference.
SATA cables and attached storage
Things tried so far
Cold. Voltage or Dividers are no help, insulted the socket and took the chiller to -15 (coolant rating)
2x MB, one with stock BIOS the other modded, both boards were completely recapped by the folks @ Badcaps
2x RAM (G. Skill 2x1m), both kits have ran DDR 590 and better on S939, TCCD timings
2x SSD, and a platter drive, all SATA, best runs first session were SATA, did try PATA first session.
With and without nForce chipset drivers, not used with W7.
Any ideas as to why the 240 FSB limit this session?

Clawhammers that I've ever known aren't OC champs, I'm sure there's a few that can go but those are easily outdone by other chips.
Newcastle chips can be flakey but tend to do well, only real thing is they will run hotter than most others will.
A Venice chip is the best for a desktop chip for bus speed, only outdone by a Newark of course. If you're taking it to -15c that may be what's up, 754's CB/CBB like mad and that tends to limit bus speeds.
If you haven't ran the board for a long time, it may just be fussy from sitting for so long but I'd bear in mind the thing about CB/CBB limiting bus speeds. I did note at that time you had it on chilled water so if you can run it a little warmer that may solve at least some of it.

It's the CPU's. Claws and NC's don't scream. OC will be very flat.
That's just the way they are.

Thanks for the replies.
Just to clarify the cooling, all CPUs were posted at 10c and tested, then I would try 5c & 0 once I started using the percentage voltage increases. The -15c was a test just to see if it would help.

Can put the 754 away and not have a feeling there is something wrong. Switched to W7 no vid or board drivers installed other than W7 supplied, dropped multi to 10 on the 3400 NC no post at 240 FSB, switched SATA cable and moved from SATA 1 to 3 still no post at 240, bumped FSB to 250, posted and made windows. Pushing the RAM & HT ended up with this. (more vcore than I like, 5c fluid)  FSB hole @ 240? |

Could be. Is that a DFI board? What bios? I might be able to help.  |

Yes, LanParty UT nF3 250GB, BIOS 6.00 PG, believe one board already using a BIOS that I got from you for the TC as I remember. Just checked a SS from the other board same BIOS info so maybe I didn't.

Wish I could find a Boardview for this board the one I got just goes to the raid bios at boot then you cant do anything.  |

Both boards I've been playing with have done that or similar, although usually cycles through if given enough time and post second or third time around, only once did I have to do a clear cmos. Only happened when manually setting FSB in the 235-240 range. FSB above 250 never had it happen again. |

Interesting my one does it at standard speeds I have never been past the raid screen.
I am going to have a go at fixing it soon.

Bones, Your CB comments made me wonder so did some rudimentary tests.
3400 New Castle, (Lied was a 3200 New Castle)
10c=277 FSB
0c= 281
-5c = 284,
285 needed a little more vCore for an error free run, only got 2 good out of 10+/- PiFast runs.
Scott, Was using a BIOS from you during the TC (AMD WP32), when I looked for my comment above only paid attention to Version not Date. 240 hole still there?
Toasted a 3200 Venus
1=Thumb screw for the VGA was laying on the board, though no damage in the area
2=Lost a pin on one of the Turions assumed it stayed in the socket, tried a Newark next that came out of a laptop I had, was doing some weird shit when I finally got it to post. Pulled it blew the socket out and mounted the 3400NC 3200NC for the test above and to see if the pin was causing the problem.
3=Mounted the Venus while the closed cell foam was still cold from the NC might not of had a good seal and probably the reason based on other evidence.
Guess it's what happens when you do shit on Friday the 13th.
Got lucky only took the CPU.
Only thing I've noticed with the samples I've played with the IMC's on the Venus are not that good.

Yes, temps can make all the difference.
I'm not really suprised things got better the colder it was but was backwards from what I was expecting to see.
Guess it can go either way.
I've had chips that balked at or above a certain bus speed once cold, others just loved it and of course you've got cold-haters in the mix too. The tendency I ran into is they would act out once they got to a certain temp, that's why I stated it the way I did.
My current 754 bus speed WR was done with the chip running warm.

Only had one cpu that didn't CB until around -50c or so. Might have been a tad warmer than that, been a long time.
356.5 bus clocks Sempron 3100+ Paris core. All the rest I benched walled hard and CB big time. Some not even capable of freezing temps.
Also to note, just for max frequency, I ran a single stick single channel on most I tried to gain the FSB.
Good Luck!

Bones, Cold bug is a problem with two of the CPUs I've ran.
3400 Newark won't post below 7c , then again it's not a real happy CPU won't go past 230 FSB and goes to shit if the vcore goes above 1.55v?
MT-28 runs out pretty well but temps have to be 5c or above.
Truth was I was little skeptical as there are more than a few SS & LN2 subs.
Everything else have not had a problem with but only been down to -5c a couple of times on some of more time consuming benches. 0 to 5c is where most have been run.

Your FSB wall bothers me. It should not be that way. That board should scream.
Has to be a reason for that.

CB has to do with the IMC not the core the colder they get the lower bus frequency take my FX60 for example the lower you go 0c is OK -5c the bus frequency drops off I am better off running it about -15 but only being able to run 220 bus and up the multi. With locked CPU's you are stuck at 0c or higher.
Windsors are better they go to around -35 without problems but -40 and they Blackout.

Some are no good, but most of them clocked decent. Even better than most Brisbanes I think. |

Scott, both boards have a hole @ 240, maybe from the recapping? The Newark just a piece of shit!
Can't find a Newark on Ebay at a reasonable price, in fact only one pops up, 4000 the seller wanted $290. $190 today when I checked might consider it if it was guaranteed to do 3.6 on stock air.

Too much for the Newark.  No answer for the hole. None of my 754 stuff does that. |

Outright robbery at that price. Even if it could do 3.6 on air that's way too much. |
