K8N Neo4-F

[srygonic]

I just overclocked my Venice to 245 from 240 and it had an error on prime. So I upped the voltage by 3.3% and ran prime95 to test it again... after 45minutes or so my computer just rebooted by itself out of nowwhere.. Is that normal?

I went straight into bios and set the FSB back to 240 and voltage back to 1.450v. When I went into windows they told me windows suffered from a serious internal error... So is this common or what?

Sorry I'm kinda new to overclocking..

I can get my system stable @ Mem 250, FSB 250, CPU 2.25 Ghz. Voltages are at: CPU: 1.5v, Mem: 2.7v, NF4: 1.6v. With this config my CPU temp under load is 42C. From what I've read thats extremely low. I'd like to up my FSB more but if I lower the mem divider to 166 or 133 I get no POST. I have Bios 1.75mod. Can anyone tell me whats the limiting factor? Also, would it be okay to up my voltages more? Any higher and it goes to the red numbers, and I dont want to fry anything.

the 1.75mod bios for me doesnt work well for overclocking. i tried many different types of bios but 1.71 beta is the best that i've seen. many of the people on this forum who have neo4-f's use that bios to achieve their high oc's. for some reason it's just more stable compared to the others at high HTT/FSB.

i never experianced that before but post your system config that might help us help you better

 

[themagic8ball]

Thanks much will try that.

 

[themagic8ball]

Still doesnt post over 240-250 FSB, and it absolutely will not go over 230 when the mem divider is less than 200. I'm really lost because I've heard of so many terrific OC's of this combo that it sucks I can't go over 2.2 Ghz.

 

[Cobalt]

Try the 1.71beta BIOS, also is your Venice new, ie. the E6 revision? I've heard those don't OC very well at all.

 

[themagic8ball]

Yeah I'm on the 1.71B and its a DH-E3 Revision. I don't know what the DH stands for though.

 

[aiya24]

you might not have enough volts on your ram? maybe 2.75-2.8v, im only saying this cause my friend has 1GB of kingston hyperX DDR400 and all he could with his 3000+ winnie was get 2.2~2.4ghz and i think he set the vdimm to like 2.7v. the point im getting at is when he upped the vdimm to 2.85v he was able to oc to 2.5ghz using the 133 divider and lose timings so you might want to try that since your using corsair XMS. oh, my buddy has a neo4 platinum using 1.71 beta BIOS but recently updated to 1.8 offical with no difference. just keep in mind he has a winnie not a venice like the rest of us

 

[Snowice]

thanks cobalt for the 1.71beta bios

 

[themagic8ball]

Cobalt what vDimm and divider are you using w/ the Corsairs? I have the same mem I think and I think that its holding me back.

 

[Cobalt]

2.8 vdimm and 166 divider.

 

[aiya24]

hey cobalt do you know if the 1.71 beta bios supports dual cores? just wondering. i've looked but i cant seem to find if it does or doesnt.

 

[Cobalt]

I don't know if it does but I'm pretty sure it would. I was under the impression all nForce 4 mobos supported dual core, only nForce 3 needed the BIOS updates.

 

[themagic8ball]

Okay the frustration continues... I was attempting to push the FSB to higher than 250 since 240/250 seems to be my limit. I decided to try clockgen so I lowered everyting in BIOS, multipliyer, divider, etc... and raised the vDimm to 2.85 and nf4 to 1.65. Booted to windows just fine and went to clockgen w/ prime95 running. Will not go higher than 220 w/o freezing! I get a worse OC the farther I put down the mem divider! Im about ready to give up.

 

[Cobalt]

YMMV with OC. Nothing is guarenteed.

okay thanks, i guess the only way to find out is to try it

Hi guys, first time poster with a quick question!

I'm about to buy an MSI K8N Neo4-F with an Athlon 64 3000+ Venice CPU, and I am slightly concerned about the bios situation - will the board recognise the CPU straight out of the box, or will I encounter some issues? Will I need to get the bios flashed prior to installing the Venice CPU, or will it boot allowing me to flash the bios at a later stage?

Apologies if this has been answered before, but I'm far too tired to remember anything of the last nine pages of posts..

 

[Cobalt]

It will recognize it right away.

Hi
I need some advice. My hardware is: MSI K8N Neo4-f (bios 1.9), Athlon64 3000+ (Winchester), 1024mb Kingmax PC3200, Fortron 350W
I change fsb up to 245x9=2205MHz and everything was ok. I boot to windows a ran Prime95 Large FFT test for about 3 hours without any error. But when I shutdown PC and after a while turn on, there is only a black screen and LED indicates that mobo cannot initialize the CPU. Then I must push restart button 20-30x or clear cmos
In ClockGen I can get even 267fsb with stable Prime95,but restart is my nightmare!!!
My settings: HT multiplier 3x, CPUv 1.45V with OverVID 3,3%, NF4 1,55V, Mem 166MHz 2,65V 2,5-4-4-7-2T
Please help.

Ok, i'm new to this forum, as well as CPU overclocking. I have the MSI K8n Neo4-f mobo. I was pushing the FSB on my 3200+ venice, i pushed it up to 225mhz, which was the maximum fsb speed without constant rebooting of the machine with the multiplier at 10x, so i made the multiplier 9x, i pushed it up to 226mhz FSB speed without constant rebooting, then i pushed the multiplier to 9.5x. THen when i pressed save and exit, the comp rebooted, then it rebooted again, and when i tried to enter the bios, there was a blinking underscore, instead of the blue bios screen. After reading lots of forums about this, i tried taking out the mobo battery overnight, then put it back in, i got back into the bios, but after i saved and exited with default settings, it would just come up on the screen that asks you if you would like to enter the Bios, but i couldn't enter the bios, and it wouldn't post either. And when i tried taking the mobo battery out again, it could get into the bios, but it wouldn't post at all. DOes anybody know how to fix this?

 

[CHOPPER GOD]

I would like to really let neo4-f users who are having problems OC'ing in the bios to forget about it and use clockgen. 0 and im mean zero problems. Just use Clockgen before you load up a game. I don't need or want to oc just surfing the web. I COULD NOT POST ever past 219 FSB back in the day and was SOOOOOO frustrated. I can hit over 300 with clockgen stable...See sig

Please help.

You have a Winchester. This board has a "219mhz FSB bug" with Winchester cores week 0450 and later. The bug is related to the HTT somehow.

should look like this roughly, although it seems to vary a bit for each processor:

FSB / HTT multiplier / result:

219/5x/fine
220/5x/no boot
229/4x/no boot
230/2x/fine
239/2x/fine
240/2x/no boot
over 249 FSB= varies per user, some have success with Winchester and 1x HTT multi. I did not, mine would hit bios bug at 219 and that was that.

to get around this, do your OC math as if you did not have bios bug, change RAM divider accordingly and then go into Windows and use ClockGen and you will have no problem whatsoever running at 320 FSB with this board. You can use a ClockGen startup file that will automatically raise OC when Windows starts rather than when bios starts. works awesome, just make sure your voltages/PCI locks/RAM speed, etc. are set up in bios before you use ClockGen or it will just freeze up.

two other points- bios 1.9 has been hugely problematic for many users. right now v1.6 official is the best bios for this board.
also, I replaced my Winchester 3200+ with a Venice 3000+ and the bios bug disappeared

clear your CMOS by CMOS button

1. use memory divider
2. NEVER use .5 multipliers, use only 10x, 9x, 8x
3. there is no way your board is locking up at 226 FSB, something is screwed up with your overclock
4. If your FSB=225, HTT multi must be 3x or 4x
5. did you raise your Vcore when boosting the mutliplier?

sounds like your PSU might be a piece of crap, what brand/model is it?

constant rebooting is NOT normal, you have either reached/exceeded your max CPU speed or your Vcore is too low to support the CPU speed

you need to slowly raise FSB using the SAME MULTIPLIER EACH TIME. you can't go changing multipliers in the middle of an OC, you are going to screw something up

if what you saw was a flashing white cursor on black screen instead of bios, then you are past your CPU's max speed

 

[aiya24]

hey, cobbler what are you temps with that oc and voltage?
