3800 goin to 2.8ghrz

i have a few questions... my 3800 will be coming this week, and im goin to shoot for 2.8ghrz with it on watercooling maybe a vapochill

i do not want my pci slots increasing, so can i just jack the multiplier and leave fsb alone for the most part, that way my pci dont have a huge increase?

also you can see my ram in sig, ddr400/200mhrz think 300-400mhrz would be good for them



( i ask these questions because i havnt fired up my bored... its in sig ... yet so i was just bein curious and figured id ask, because i dont know what all options its goin to have )

ive read it 4-5 times, but just cant seem to find where it states wich overclocks for pci's.... i do plan to set them on locked rather they will stay that way or not

Technique 2 - Raising the Core Clock
This is the probably the most common method for OCing since AMD and Intel have implemented locks on their processors. The good thing about this approach is that you have a lot more control over your OCs i.e., for each MHz you OC the FSB/HTT, you only OC by the amount that is your multiplier which becomes useful as you try and get a feel for your maximum clock. The down side is that you also increase the operation speed of the memory and if you dont have AGP/PCI locks, the speed of the AGP/PCI bus. Not all memory and/or cards can handle the increase in speed so thats why people run into problems.

thats the only thing ive found about pci's.....so basicly is what im asking is, if i dont raise the core clock, my pci's wont increase if i have them locked?

my goal is 220fsb X 13multiplier = 2860 ...hoping to have close to stock voltage and i wont have to worry about temps id ont think


i also wanna ask, since i plan to go up by 10mhrz at a time... i cant really do that with the multiplier, should i use the fsb and multiplier together firs to check for stability, then if 2.8ghrz is stable, go ahead and set my fsb and multiplier to what i have stated?

Your board has PCI and SATA locks, so you can raise the FSB without worrying about that. Your multiplier, however, is locked, so you can only OC by raising the FSB (HTT). This means you do have to worry about your RAM.
I like finding each factor of my overclock seperatly. I isolate each variable seperatly by lowering every other factor. Then I combine all the variables (such as max CPU, max RAM, max FSB (HTT), etc).
 
ic, see now that makes me understand better...ty

is the multiplier locked @ 10?

so basicly, as long as my ram can handle a 80mhrz, increase... then i should be ok

last question then im done... voltage stock for 3800 is 1.3-1.4volts i believe, what in your own opinion is the highest voltage i would wanna go

Yes, the multi is locked at 10 X. This guide over from DFI-street is pretty helpfull at understanding overclocking with that board. http://www.dfi-street.com/forum/showthread.php?t=20823

Are you really going to get a phase change unit? If so you should be able to push it up to 2.8 Ghz easily, but be prepared to raise the voltage a bit (or a lot). For air I dont like going above 1.55-1.6, but phase change should be ok at higher volts.

EDIT: Ku-Sama its an X2

yea i have my own built watercooling system about finished im gonna try it out, and overclock with the x2 3800, see how the temps are.. if they get hot wich i doubt, i will be goin to a phase change then i wont have to ever worry about temps agian :p

so what do you think about my memory.... should be a good overclocker?

note im asking all this because im just waiting on the cpu to get here and im very anxious, currently on a presler 920... so i cant stop thinking about how this amd change is gonna be

also, whats a recommended voltage from you personally... from 1.35-1.4 stock voltage, basicly.... whats the max voltage u would go to then tell ur self to stop even if it was stable and cool temps

The real killer for any cooling system is volts. You can have a CPU running at 1.9 V and @ -100 C but still get fried. 2.8 Ghz is going to be pretty hard, just warning you though. Dont rush with it just go step by step, and if you've reached your limit dont push it harder.
 
per say, your stock voltage was 1.4volts... whats the highest voltage you would tell ur self to stop at.. even if it was stable and cool?
 
ive been reading quite a bit about the ldt/htt im new to the athlon 64 chips, do you recommend i keep the HTT on auto?
 
no, keep the frequency under 1ghz for hypertransport. of course, if its above 1ghz and never freezes or anything then it should be fine but normally it would cause instability. besides, hypertransport doesn't effect system performance alot anyways.

also, make sure you have a nice power supply with plenty of volts per rail.
my psu won't let me overvolt my cpu at all, im planning on buying a 680watt aspire for $100 soon though.
the great thing about water cooled systems is that you can add radiators. if i had the money (and the patience) id do that. lol
id say you can reach 2.8ghz but you'll need plenty of volts and definitely a nice power supply.... and ill bet cpu life will be cut in half even with water cooling--- heat can only move so fast!

volts???? what the heck do you mean volts, did you mean amps?

do you mean you mobo? the psu will always let you, it just may cut out

again there is a trade off

again with the volts, i think a read of psu101 is called for
 
i think i was asking for a too high of a goal the more i think about it, it hink im gonna shoot for 2.6ghrz instead of 2.8ghrz... thatsa nice overclock either way 600mhrz

also my psu is in sig

i will keep you all updated how it goes soon as my cpu gets here

uhh YEA it cutting out would mean it WONT LET YOU. wow.
sure AMPS whatever the psu was bottlenecking my overclock... he still shouldnt get a crappy one.

EDIT: i trust the psu, ive never had an aspire but it seems to be popular.
 
ive read it 4-5 times, but just cant seem to find where it states wich overclocks for pci's.... i do plan to set them on locked rather they will stay that way or not

For someone wanting a 800MHz OC on a Vapochill .... shouldnt you know the PCI bus is already locked?
 
no i didnt exactly... i read about it, i just got into overclocking like a month ago, ive always been into building show pc's and such


and ive always had an intel... this is my first amd, i dont even have it goin yet, im waiting on the cpu to get here... is why im asking all these questions now

also i new their were pci bus locks, but i was under the impression from a few posts that sometimes the locks dont work when u overclock alot....etc etc
