Over clocking a Duron 800

[davesalisburyuk]

I have a AMD duron 800 on a gigabyte GA-7IXEH, my promblem is that when i try to o/c the cpu it will go to 906 114x8.0) fine but when i take it any further when restart and go into windows ME it says windows has encountered registry promblems restarts and clears the windows registry or it does'nt start up and i have to clear the cmos memory i am using a 1.5gig aproved fan, i also have a program called easy tune which can o/c the cpu from windows is that any good? The cpu runs @ around 60*c when i o/c it to 906 is that normal?

[iggybaseball]

wow, u might want to watch the cpu temp on that. My duron 800 is at 850 at its only 31C. Also check to see if ur vid card, or mem or any pci device is holding it back but ur temperature seems really HIGH:eek:

[lonewolf1983]

that seems mighty hot
if that fan is rated to 1.5 gig there is something wrong
make sure the fan is working,and that the heatsink and the heat transfer compound are alright

what voltage are you running it at?

[iggybaseball]

what kind of cpu compound do u use? Is the heatsink on right?

[JAWS]

Usually you would increase your vcore for some stability. What do you have yours set to? 60c is way to hot for my liking! I would reset your h/s fan just to be sure!

[davesalisburyuk]

I dont know how to change the voltage core i am using heat sink sealer compound and the fan is mounted right.

I wouldn't worry about changing your vcore until you can drop your temps.

As the other kind folks stated. 60c is wayyy to hot. You will definately damage something in time. Check the mounting, look at it from the side if possible. I've always placed my hand down on it, and see if it's to hot to the touch also, but I guess you know it's at 60c? I would recheck, and re-seat.

I think i have a crap fan can anyone reccomend a decent fan that will keep me duron 800 cool the most it can be overclocked to is 960 i want to do that also it would help if i could buy the fan off the net. my voltage core is 1.6 but how will i change it when i get a better fan? thanks for all help

[killem1x1]

If noise isn't an issue, then pickup a big delta screamer. I prefer the Sanyo Denkis, although they are stealthy they will not give the same cooling performance as the delta screamers

You will have to check your mobo manual to see if you have the vcore option. If not the only thing you can do is connect the L7 bridges on your cpu.

[davesalisburyuk]

Do i just join the top and bottom L7 bridges together? will it do any damage and will i then be able to adjust the v core and how high shall i take the vcore to my m/board has'nt got a setting to adjust vcore. also where can i buy these fans on teh internet

[JAWS]

When you connect the L7's on the chip, it boost the voltage to 1.85. If your mobo doesn't have vcore options than your stuck. (but it will be better than your 1.6) When the front page comes back up, look for the help guide on connecting your bridges! Here's a good site for your fan: http://www.crazypc.com

ummmmm..........
My 1gig @ 1350 hits 35C max load...it is winter though. Room temp 25C.

[Slychilde]

What HSF are you using? It sounds like you need a new heatsink, not a new fan to me. If you haven't looked already, there's a good listing of socket a hsf's and how they perform here: http://www.overclockers.com/articles373/

I know everyone else said it, but I can't stress it enough..that is too hot! Something will break. Lower your temps before you try to push more outta it.

1.6v will only get you so far, like JAWS said :) If you can't find anything in your manual about Vcore (that's what you're looking for), then pencil them bridges! 1.85 is a pretty safe voltage and should help out.

[Maximus Nickus]

I doubt 60C will damage anything just reduce its life although you won't notice it unless you plan to use it for 10 years!!!:eek:

It would be unstable though, my T-Bird hit 95C twice when the fan fell off! Once I was ok then the board blew, it was a pants board though really s***, some Jetway 663AS Pro....

Lovin my new Epox!

60c may not damage anything, but may being the key word. Not a temp any serious cpu user would even consider using imho.

[Maximus Nickus]

Look @ the AMD website.

Anyways you seen how hot PC's you buy from a shop are? They have no case fans at all (in or out) just a PSU fan with BAKING HOT air coming out!!!

Well that was the P/IV I saw @ PC World last week!

I am waiting for a board and a 800 duron the mobo doesnt allow voltage adjustments in the bios or with jumpers so I am going to modify the L7 bridges using a conductive ink pen. You can compare you bridges to this and adjust it accordingly.

You can buy fans here www.sidewindercomputers.com (http://www.sidewindercomputers.com) or at www.millisec.com (http://www.millisec.com) both are credible dealers I've used both without any troubles.

[The Overclocker]

to get a good heatsink and fan go to www.overclockingstore.co.uk (i think you live in the UK) and buy the SK6 heatsink and some artic silver thermal paste

[Maximus Nickus]

Connecting the L7's simply sets the default VCore to 1.85V which is the highest most boards with adjustment can get to anyway, without a Volt Mod that is....

[davesalisburyuk]

1)Can i connect the L7 bridges using a pencil? also what will i gain by raising the vcore?

2)Has anybody succsessfully connected L1 bridges to o/c the cpu on a duron if so what does that gain aswell. Because the most i can take my cpu to is 960mhz (120x8.0) how can i get more out of it.

3)Also thanks for all heatsink help i have ordered a cooler master DP5-6I11A has anyone used this fan is it any good? and i have also ordered 2 delta screamer case fans if that does'nt lower my temps i dont know what will!!!!

1. Yes you can, it won't wear out unless you rub it out! Or take the HSF on and off, when you oc your CPU needs more power to maintain stability, so by upping the VCore you can run a higher speed.

2. Connecting the L1's unlocks it, this allows you to oc your CPU via the Multiplier (if your board can change it) however oc'ing by your FSB is faster as everthing is oc'ed!

3. I would reccomend the Swiftech MC462-A, its about $80. (You will need a shim though as its so heavy to protect your CPU's core.) Use 80MM Ys-Techs or 120MM fans as they blow out much more air than the Delta Screamer 60MM fans, oh and with the Swiftech if you get it use a 80MM DELTA for best performance! (60CFM! or more....:eek:)

However it will still outperform any other HSF even with a quiet fan.

Hope that helps!

So if i connect all the L1 bridges will i be able to overclock it past 960mhz because in the bios the fsb will onl go to that so if i pencil in the L1 bridges wil i get it past 960mhz

If you don't have the option to change your vcore in your bios, don't worry about the L1's.

[Maximus Nickus]

ummmmmmmmmmm

Your way off!!!

Pencil the L7's to get more voltage, then put the FSb higher!!!!
And if you can adjust the multiplier higher then connect the L1's and do that, if your board is at its max fsb already then you can't do anything apart from mod the L3's / 4's on the chip and change the multiplier on that.

I did it but I don't reccomend it, as you can knacker ya chip!!!!

Although I don't know of anyone knackering it this way, unless theve shorted it out by connecting two bridges next to each other together....

[LinkStatic]

seems that u have a KT133 chipset on that mobo... limiting your capability to up your FSB any higher...

the need to Pencil the L7's comes when your overclocking to high and the CPU's default voltage is not able to handle it at POSTing. Getting hiogher default Vcore will overcome this problem...

You still need to Pencil the L1's so as the BIOS functions to change the Multiplier will work...

MAX Multiplier + MAX FSB is the way to OC.....

Hope this helps you....:)

[davesalisburyuk]

So if i connect the L1 bridges will i be able to take it past the limit on the motherboard which is 960 (120x8.0)? thanks

Without doing anything! If you can go right now, and change the multiplier in your bios, connect the L1's. If not, don't!

Exactly if your max fsb is 120mhz and you cant change the multiplier with the bios or with jumpers then its useless to connect the L1 bridges. If you can run stable with the duron @960 120x8 then you dont need to modify the L7 bridges.
