Fsb problem with Neo4 Ultra

Question

I have been having a problem with my neo4 ultra that seems to be pretty common.
I can not boot past a fsb of 219 reliably.
My system is
AMD64 3200+
MSI K8N Neo4 nForce4 Ultra
Wavemaster Case
OCZ Gold Series Dual 1GB DDR PC-3200
Thermalright XP-90
OCZ ModStream 520W
Sapphire Radeon X800 XL
I am doing it all with clockgen to up my FSB to find the best results. I am on 1.24 BIOS
My Basic BIOS settings are
FSB = 219
HTT = 4x
Mem at 166 Voltage at 2.85
Mem Timmings at 2.5-3-2-8 1T
CPU 10x startup - cpu-z reports voltage at 1.58
Rasied FSB by 5 at a time to 251 and super pi failed.
Changed vcore to 1.60 and the best I could get super pi to run at was 247. So I decided to start fine tunning my memory.
I set mem to 180 2.5-3-3-10-1T
Used clockgen again and what was interesting was FSB of 255 passed with a superpi of 34 sec. Now it failed at fsb258.
Changed mem timmings to 200 2.5-3-3-10-1T
And best I could get was fsb=230 and superpi failed. I decided to keet the 180 divider and see how far I can drop the timming at 180.
So I ended up at this
FSB =251
HTT 4x
Mem 180 2-3-2-8 1T volts = 2.85
CPU 10x Volts cpu-z reports 1.63
Runs prime stable all night at these settings.
But here is the thing if I go into the BIOS and change fsb to 221 My machine will not boot.
I am guessing the power up sequence is wrong in the BIOS

Answer 1

I cannot boot at over FSB 219, either. Will overclock fine with Clockgen when in XP (have tried up to 270 fsb, and the CPU will run 2574mhz at 1.5). But have to reset bios if I set the FSB over 219, regardless of memory HTT, vcore, etc , settings. I've been watching other forums and have seen MANY people with the same problem. One of the things I have in common with a lot of other people with this problem is that my Winnie 3500+ Retail will not run much over stock with the low vcore that this board gives as default. I have used Core Center, Sisoft Sandra 2005, and CPUz 1.27 to check vcore once in windows. All of them show 1.36 for vcore. That's lower than default of 1.4. And when I set the vcore for 1.55 and the overvoltage thingy to highest percentage in bios, all the monitoring apps show 1.526, which is waaay lower than it should be (1.67). Now, I will concede that the monitoring apps could be wrong. But, I believe the 219mhz POST issue is due to the start up vcore and multiplier is PROBABLY default at post. So, if your FSB is set for more than the CPU will run at it's default vcore and multiplie + set FSB, then the board freezies at POST. If the bios would just boot at whatever you set into the bios, then there wouldn't be a problem, unless yoiu have set thingswaay too high. Then it would just do what it does now, not POST, and you would have to reset the bios. There are a lot of Winchester core CPU's out there that will run high mhz at default voltages. But, there are a lot of newer Winnie's that won't. Mine is one of them.
Now it seems that there is a limitation on the board of 1.55 vcore with a Winnie. Even using the overvoltage setting. What is that all about? You put overclocking friendly on the retail box, on the product page on the main site, and all the review sites say overclocking potential is graet, and then you limit the vcore to 1.5v? Crazy logic (or should I say "Fuzzy Logic")   I am close to eBaying this board (only had it 2 - 3 days, but won't send it back to ZZF for replacement as all of them could have the same problem) and go with the DFI or the Abit Fatality.
Am I saying all this right?
