Not really sure about that one... Do you have enough cooling?Quote:

Anyone have any idea why that happens for me?
Well, 2600+ and memory is holding me back now... I know for certain it's not my A7N8X board :P When I wake up tomorrow I'll try and prove that 100% by using my Kingston hyper x in 1 slot to show that it's my memory holding the fsb back. And as for the CPU holding me back well, it's not going much past 2.6ghz :(Quote:

I think i´ve found the problem. I read somwhere that when the computer first boots it don´t use the extra voltage just the maximum of 1.85v. So that´s why it wont boot for me att higher speeds.Quote:

Seems like the only way to fix this is to put som copperwire in some of the holes in the socket. But I hope it is something that can be fixed in a new bios release.
altair4 I would look real hard at your PSU 5v rail, I don't know what video card your using or the rest of your system but the A7N8X uses the 5v rail for vcc, if your using a R9700 Pro then your 5v rail is taking a beating. After I did all of the mods to my A7N8X and R9700 pro I went through 3 PSU's b4 I found one that didn't go below 10% on the 5v and 3.3v rails under load.
I have an Antec Truepower 430w and it has never dropped under 10%. I also have R9700@PRO clockspeeds.Quote:

The strange thing is that if I don´t shut down my computer I can run fine on higher voltages, it´s just when I shut it down that it wont start. It seems that if I boot at speeds that needs the extra voltage to boot, then it fails. But just restarting from ie. exiting bios works just fine.
I too am useing the Antec TP430 PS and never had a problem. The extra draw for the vid card seems to not overload a thing for my system. Before this PS.
I used the PP412 and it is still in the system the wife is using, same A7N8X/dx system no problems on that system either.
I just do not understand that some people have to use a 550 watt or even higher in order to run stable.
Cool mang -nice score :banana:Quote:

Let us know how ya make out with the new gear... geeeezus I wish you would get that killer cooler running .....:D
The "problem" with the freezer is just that I need to buy some tubing, and some plumbing for it. Other than that it's ready to go. I'm gonna try to have computer cooling ability in a week or so.Quote:

2800+ Barton will be here tomorrow before 3pm! Woot!
Also guys! Check it out! I know all of this info is kinda mute for you guys as we've all discussed it here, but I've put everything I know for the A7N8X into a modding guide ;)
http://www.maximumoc.com/guides/a7n8x_modding.html
Ok don't listen to me, test your rails by running mbm with alarms turned on for the 5v, 3.3v and 12v line, set to 5% tolerance, then run 3dmark.
Wewt.... my 2800+ Barton came!
AQUCA 0306TPAW :)
Rest assured it'll get nailed with benchmarking and overclocking today.
Dos your sound stil craps after aprox 200 FSB ?
Nah, with the VDD mod I get sound 230mhz + :cool:Quote:

Also, I have been oc'ing my barton, yes. I am going to do the other cpu vmod though that allows up to 2.3v before I continue with the OC'ing.
Is it any way I can get Higher @ this is on ASus A7N8X on Air colling Vol7+ Not V-moded and a 2200Xp A-core :(
Prime stable for 1H
2094.75MHZ
220.50 System clock
441MHz DDR
Multi 9.5
Sure! A chipset vmod! :P
I wish I could do it LO l
Im going for at chipset-Waterblock this week, and then a new soldering iron.... I did the Vcore mod and it wasnt hard, the vdimm actually looks easyer. But the vdd is very small thats why i need the new soldering iron :)
I hope for 230+ on the FSb and better timings (2-3-3-7 atm)

Edit: Any suggestions on a block for chipset? I have been looking for comparing reviews but theres not much around, maybe the block isnt as critical as CPU?
I can't get even the slightest performance out of my A7N8X Dlx. Any tip would be welcome. Components:
ASUS A7N8X Deluxe rev1.03 Bios1003U
AXDA1700DUT3C @ 2.1Ghz (12,5*166)
ALPHA Pal8045, Papst8012 26.5cfm fan
Corsair TWINX512 CMX3200LL
Abit GF4Ti4200 OTES
With that system I seriously expected to hit at least 200Mhz FSB, but there's no chance, anything past 175 will make the system unstable. I've tried various voltages on pretty much everything (allowed by the Uber-bios), maxed out RAM (2.6-2.9V), maxed out Chipset Voltage (1.6-1.9V) etc. etc.
I notice that my SB-chip gets VERY hot, and the passive sink on the NB gets rather hot too. Other stuff that could cause problems: PSU (300W), but all voltages look ok, no fluctuations, as close to spec as I could hope for. I've disabled SATA with the jumper (don't have SATA-disks yet) and currently don't use any 1394-ports (disabled in bios together with com1/2 etc.).
I really think I should be able to reach higher FSB, especially with the RAM I just bought, matched pair of CMX3200LL's, 2*256mb.
I don't have any cooling on the SB/NB though... Could that be it? Getting frustrated. Also, would a better fan on the Alpha help me go past 2.2Ghz on the 1700Tbred-B?? Is it likely that I need to do any modding to get even higher voltages to get the bandwidth I want? It sucks to run the RAM @ 333Mhz (no, I don't want to go async).
*begging for mercy*
ps. I did manage to boot @ 200Mhz, but the screen was garbled with broken dos-text etc. agp-freq. was fixed at 66Mhz.
Try moving your FSB jumper to 200 from 266/333 ... That SHOULD do something for your max FSB ....
/Damir
Good cooling on chipset should help u, I had like 7-8 fans in the case and I could do 210 FSB, after going to WC (On CPU) and removed the fans I could only do 170, because of heat!
Therefore I have ordered a block for my chipset ;)
Thanks guys. Another thing that made me suspicious of the heat/performance of the chipset was the fact that when running the chipset at 1.7V the Soundstorm clicked, I got some disk errors etc. and when I lowered to 1.6V it turned out ok again.
Time to order me a few fans, sinks and make a few holes in the case.. ;)
The über bios doesnt really work. So perhaps sound just clicked because of heat
I've RMA'd the board. Even when running 12*166 (lower than the RAMs spec.) I get the "System failed memorytest" one time out of four. And that's without any voltage increases or overclocks at all.
Somethings shady with that board.
hi there, and sorry for the issues,Quote:

but what I recommend is to rma and get another board, the good boards must be able to reach 200mhz without any mods,
I have try many boards and I can tell you this if it doesn't reach 200mhz stock, it sucks:rolleyes:
You want a board that can reach 200mhz stock, so you can increase with mods, getting to 200mhz with mods is just plain wrong:mad:
Just thought I'd post up a segsy picture of a board I just modded for someone. A lil eyecandy ;)
Oh btw..... I WANT ASUS ULTRA 400!!!!!!!!!! WAAAAAA!!!!!!!
