Hey guys,

This r my settings

Q9550 E0
P5Q DLX
4X1 GB Crucial Ballistix Tracer 1066

Previously, i had my mobo being blasted by lightning and had to RMA. Now, the rma mobo is back and i upgraded the bios from 1004 to 2005 cause previous bios(1004) cant OC even at minor like 350mhz. So, upgraded to 2005, it seems the problem remains the same as previous version 1004. I wanted to use the first bios for my mobo which is 0803 but not available in Asus website

Any idea hw to solve this problem and have my rig OC for performance? Helps are appreciated.

Thx

Are you even sure what you are doing is correct for overclocking?


Perhaps you can tell me what you do to overclock your pc and I may be able to quide you abit

list out all the OC setting like fsb, multiplier, voltage, ram multiplier, timing.....etc...............

are u sure u already know how to tweak ur rig?

wrong section btw. this should be in OC section.

I did what most OCers do but due to my knowledge isnt as vast as u guys. I will give out the details

CPU ratio : 8.5
Dram : auto
frequency : auto
dram settings : manual
vcore : 1.26v (360mhz)
vtt : 1.54
pll volt : 1.24
dram volt : 1.9
northbridge : 1.24

hope it helps

Added on August 3, 2009, 9:09 pmYea i am sure cause i did quite an amount of research before i tweak...its just tht after this lightning incident and RMA back the mobo, i cant OC easily like before

---

Added on August 3, 2009, 9:21 pmlets start with the settings before i did the bios upgrade

FSB : 360
Multi : 8.5
Ram multiplexer : Auto
Freq : Auto (400 or 333)

Vcore : 1.26
vtt : 1.54
pll : 1.26
dram volt : 1.9


any more infos, just ask me

set ur ram @ x2 (1:1 ratio)
timing fix it to 5-5-5-15

after happy wit CPU speed den only adjust the ram speed, den timing.

i did the setting before although after the setting is done which is from 1066(5:6) to 360(1:1) it still doesnt post a thing and the fan on gc is at 100% speed with crucial lightings not even blinking at all and thats the end of my OC for 360mhz as a start

try up the fsb voltage.

or

try using 1 stick of ram 1st.
to eliminate dat it is not ram problem.

den u can try ur processor on ur fren's pc, to eliminate processor problem.

Well, i tried the ram sticks on my another newly build pc and it works fine and can be OC but if proc cant OC after tht lightning incident, does tht mean im no longer able to OC forever ??

well, if really the processor issue, there is no stability problem @ stock speed just cannot OC, u can't claim warranty......

try increasing the vcore to 1.4v just to see whether its the usual case of not enuff voltage supplied.

eh 1.4v for 3.0ghz....thts really insane for Q9550 isnt it. Just saying not discriminating sorry bro

Added on August 3, 2009, 11:48 pmSo, even like changing the multiplexer to 8.5 will cause instability ? Oh great....there goes my great proc

This post has been edited by his: Aug 3 2009, 11:48 PM

im suggesting that to eliminate the possibility that not enough voltage is being supplied.

if it does u can always lower the voltage later.

ok i will give it a try

---

Added on August 4, 2009, 1:18 amnope....problem remains the same. Guess Tech is rite, i cant OC anymore

This post has been edited by his: Aug 4 2009, 01:18 AM

still, stress test it wit IBT or something.
if it doesn't passes, @ least u got something to argue went u sent for warranty

bro tech, i do stress test with OCCT n prime95. Do u mind explaining in more details abt the argument of warranty ? Thx for the savings.

*OCCT on Large Data Set keeps failing and indicating core #3 after 9 secs *

This post has been edited by his: Aug 4 2009, 01:47 AM

me OC my bro 2.1 to 2.5 with 1.56Vcore! didnt realize it at first coz the bios is different from mine.

but change it afterward.

try IBT, if fail.
u can go claim warranty.
as long as retail & within 3 years.

IBT test shows tht on "High" it shows error but on "Standard" it hows success. Do i continue on for the rest of the stages or sent it for warranty? thx for the guides

it shud pass maximum @ least 5 loops.

I aint sure whats going on during IBT...first round testing error but when it comes to second round, success. Any clue

dat means not stable...........

try wit OCCT, choose to only stress the processor.

It doesnt seem to get right at this point...yesterday shows error on "Maximum" in IBT and OCCT Large Data Set keeps prompting error on core #3 in less than 10sec.

Today, i start IBT and OCCT...both r fine and indicating no error until OCCT reported error on core#1 and thts it no more errors after a few stress rounds.
Can anyone figure it out

it shud b smooth sailing 24/7.
but stress testing failure can also cause by other h/w such as mobo & ram.
try & put ur processor on another system & try stress testing again.

processor is design to run @ full load 24/7.
so it shud passes those stress test. 5 loops of IBT is consider as ngth, it shud b smooth sailing.

if indeed the processor got problem, u can argue to intel bout dis.
say something like u ran folding 24/7 & processor often causing crashes.

Run OCCT small data set for cpu stress test...
OCCT large data set failed = incorrect voltage or timings for Ram & vNB...
Set Cpu Margin Enhancement to Compatible or Performance.. (if any)

Since Core 3 is giving premature failures on IBT, I would suggest to send it for a RMA claim

To kill your processor, continue using IBT and have it looped non stop for the next 2 days, that would literally kill your processor.

The bolded.. that seem not right. R u sure?
Did u use the old power supply that involved in the lightning tragedy? I suggest that u try other PSU. It could be your PSU.

bro bryan, although i know tht proc are literally the most non effected hardware in terms of nature disasater unless of course some high generated voltage did overburn it. But if u say kill it off, hw would i be able to explain to them and is this gonna give alot of hustle work ? sorry,,just to new abt killing off a proc using IBT

---

Added on August 4, 2009, 4:27 pmbro tech, if lets say i sent the proc to Intel and inform them like what u told me. Will they take the proc for their own testing to confirm or just RMA it and wait for a new one ?

---

Added on August 4, 2009, 4:30 pmPsu is fine, did a testing on other rig. Its just tht i forgot which is which since i didnt OC for quite sometime after the RMA mobo came in and failed to OC. Any info, do ask me. Thx for ur concern

This post has been edited by his: Aug 4 2009, 04:30 PM

Hmm... btw killing your proc using IBT stressing isnt a great idea... you could kill your RAM and motherboard in the process...

Ok... put everything in stock and stress your PSU using OCCT for 15 minutes... report back to me...
What's your stock CPU VID?

This post has been edited by campsol2k: Aug 4 2009, 04:41 PM

its all in stock settings, change none at all...current CPU VID is at 1.25v.

Psu stressing is a success without failure/error

This post has been edited by his: Aug 4 2009, 05:19 PM

Ok. Seems that the PSU is fine. So the question is which is the culprit? its either motherboard, RAM or processor?

right now, lower the multiplier to 8 and run an IBT stress test at the last stable-unstable FSB with your previous other stable settings(mem clock/mem timings/voltages). I want to make sure its either the proc or the motherboard.

What's your PL setting when overclocked at 360FSB?

This post has been edited by campsol2k: Aug 4 2009, 05:48 PM

u 1st hav to answers some question & fill up some forms.
call dem & dey will email to u.

after dat intel will send delivery guy to ur location to pick the processor up.
now the processor is wit dem, obviously dey will test it.

u just hav to wait now.
intel warranty is usually quite fast, nvr > 2 weeks.

Hey guys

it seems i manage to OC back but with different kind of settings.

FSB : 360
Multi : 8
Fsb Strap : 400
Dram Freq : Auto
Dram Timing : 5-5-5-15

Settings for current from Vcore onwards are all AUTO.

Hope it helps giving u all a bit clues

This post has been edited by his: Aug 4 2009, 11:00 PM

hmm...

If u don't mind do some more experiments...
Try to increase the FSB become 3.0GHz (370X8) and run the stability test... Keep increasing the FSB until u achieve unstable FSB. U may test it with different multi.. let say 7.

If u can't push your processor above 3.0GHz, that's mean something is wrong with the processor.... I'd say it's time to RMA the proc...
Just for your reference, my Q9550 C1(default VID is 1.15V) doesnt need any core voltage increment and stable when clock at 3.0GHz. I believe your Q9550 E0 can do abit better... i mean when your processor is in perfect condition.

Thx for the reply...i will try it but if i up the voltage on dram (which i did tried earlier) & also increasing a slight increment on ram freq, it just runs 100% fan full speed with no post

Added on August 5, 2009, 11:06 pmHey guys,

I need to ask for ur experiences. I currently did some OC testing and below r the results

FSB : 400
Multiplexer : 8.5
fsb strap : 400
Dram freq : auto
Vcore : 1.31
PLL : 1.54
Vtt : 1.24
Nb volt : 1.22
Dram voltage : Auto

Result : No post and fan keeps running 100%

Second testing with slight changes on above settings

Fsb : 400
Multiplexer : 8.5
Fsb Strap : 400
Dram freq : auto
Vcore : auto
pll : auto
vtt : auto
nb volt : auto
Dram volt : auto

Result : Able to run and insert windows without a problem

Whats causing the problem?

as for my settings for q9550 @ 3.4ghz..(just reference ah. dun follow exactly cuz diff mobo diff settings for stability)
400mhz x 8.5 = 3.40ghz
cpu vcore 1.25
den the other Voltages, i din set auto.. i key in the defaults values instead..

den mch i bump up 0.6v

as for vdimm(vram).. 2.04v.. timing 5-5-5-15..

i think q9550 dun need alot changes to make it to 3.4ghz.. im pretty sure at stock voltage 1.25v.. it can run. i saw ppl using even lower vcore n still stable..
i think important is ur mobo mch and vdimm.. check ur sticker label for ram wats the voltages.. normally if auto, the bios set the ram voltage pretty low..
i think in bios ram voltage they usually set to 1.8v for auto.. its way below wat is recommended by the ram manufacturer.. like i say earlier.. check ram sticker for default voltage to run..

Hey guys

New update from m havoc wreaking PC
Below r the testings

FSB : 400
Multiplexer : 8.5, 8, 7
FSB Strap : 400
Dram Freq : Auto
Dram timing : 5-5-5-15
Vcore : 1.306
gtt : 0.370 / 0.410
pll : 1.52
vtt : 1.24
dram volt : 2.00
nb : 1.22

It runs perfectly but if i upped the gtt to 0.400/0.410, it wont run anymore

Second setting :
FSB : 410
Multiplexer : 8.5, 8, 7
FSB Strap : 400
Dram Freq : Auto
Dram timing : 5-5-5-15
Vcore : 1.326
gtt : 0.370 / 0.410
pll : 1.52
vtt : 1.24
dram volt : 2.00
nb : 1.22

It doesnt run and even when i upped the gtt to 0.400/0.410, it still wont post

It will only post when i stay below 410fsb and gtt at 0.370/0.410

ur OCing quad core .
y not reduce d multiplier until like 4-5 ?
and put d vCore to stock vID and push FSB bit by bit .
im saying like 333x7 = 2331
400x6 = 2400

u get wat i mean ?
keep d speed at almost identical as stock and find d stable spot for it .

raising speed u can add multiplier and vCore only so wont be hard .

bro why don't you up your vtt and nb voltage slightly and slowly to see if it does the trick. coz from what I can remember, those 2 looks kinda low to me. I suggest up with the nb first. use the bold'ed setting, but only play with the nb (first) and vtt
