Got bored 2day, started ocing, got to 3.38ghz(My comp. properties), bios(3.39ghz) cpuz(3375mhz) on pretty much stock volts except vcore(set it to 1.31), all the others Ive changed from auto to lowest i.e: FSB Termination-1.25, SB Vcore-1.05, SB-1.5,NB Vcore-1.3, DDRII-1.8v, chipset.., etc... Booted into xp seems to be stable coz im still typing...haven't tried any stability tests yet, temps dont seem to change neither, but the thing Im woried about at the moment is FSB being 1500mhz(cpuz) - is that normal? should I keep going is it ok to go above 1500fsb? Also any suggestions will be very helpfull, thx.
Forgot to mention its 375x9

Saved oc to profile1 and returned everything to standard(auto) just to make sure idont fry anything yet.
 
OCed system been runing just under an hour and froze in windows... What voltages should i increase? coz in bios theyr all on lowest. aslo if my ram timings are 4-4-4-15(says on the box), but in cpuz theyr something like 5-6-6-10(16) - should i somehow try to bring them down to 4-4-4-15?
 
Increase the northbridge voltage, and maybe the CPU voltage just a bit.

And the FSB is QDR, so 375 x 4 = 1500

There should be options in your BIOS under memory timings, or something similar, to adjust your RAM To 4 4 4 15.
 
Got to 3.7 stable in win(been on about 30 mins then i restarted & loaded standard profile, 1.45v looked a bit scary).
Yep, Ive disabled - Set ram timing by SPD and more options appeared with 5-5-6-10(something like that..), but i got no clue how to work with timings so didnt dare change them. Do you think I should set them to 4-4-4-15? or leave em as they are?
Also got to over 3.8ghz with 425x9, took the screenshot but as i was about to save it got to blue screen - do you think its the top oc for this system?
Heres a screen with 3.7 and some volts:
 
My ram is 800mhz, when set to 410x9 = 3.69ghz, in bios my ram becomes 820mhz, so if I go any higher it gets higher too... Do you think my ram won't oc any more than over 820mhz?
Because I dont think two weeks pased since i got this rig, so i can exchange ram too for a 1066(1000mhz) version, do you recon itll give me a better overclock? Thx.
 
If you want to see if it's your RAM, lower the multiplier on your CPU to eliminate it as the bottleneck, and raise the FSB more to see how high the RAM will go. :)
 
Lower it to 8x? or below? I think i still got SpeedStep enabled - do I need to disable it?(like cool&quite 4 amd)
 
If I recall correctly 1000mhz was a case with 939s(SD3700 especially) - most people prefered to oc them to something like 2794mhz so FSB would be exactly a 1000Mhz. I oced mine passed that and it was still rock stable.

The a64s were designed for 1000mhz hyper transport bus, fsb is different. Since you are using intel now, you dont need to keep it around 1000, so that isnt the issue. Definetly rule out your ram by lowering the multi a few steps and see how far it goes, try adjusting ram voltage and timings, and if need be set a divider for ram, 1:1 isnt as important as it used to be. Just take soem time to find a good balance between max cpu OC and fastest ram speed. CPU speed > ram speed, if you have to choose one to be higher.
 
Thx for replies guys, its just that new cpus with 1333bus haven't been released yet and i somehow managed to get up to 1640mhz scares me a bit even though I thought woudn't give a crap about this cpu when ocin(that was b4 i bought it), but coz all games run f***ing fast all maxed out(on 12x10) even at stock makes me wanna keep it cool - if you know what i mean.
Next time when ill be bored(probably 2morow;) ) Ill try ocing it further and lower the multipler, but tonight I really cant be asked. May be someone'll post more suggestions
 
Tried lowering multi to 8x caused some serious lockups even in bios(was hard to clear cmos), tried disabling stuff like C1E didnt help. Instead i raised vcore to1.525(bios), ddrII to 2v(bios) and used 415x9 ddrII was 830mhz, ran nV stability test for all components for 10 minutes so far so good. Also tried 420x9 - it boots into win but after 1-2 mins get blue scren. Tried raisin votage even more to 1.6v(bios) and ddr to 2.2v and try 430x9 it posts but half way there when xp logo is loading it just restarts. I dont thinks its temps, because tried leaving case opened with AC on 21c still same thing.




also tried setting timings to 4 4 4 15 didn help...
in bios if i go above 1.56vcore - it lights up in red and when ddrII set to 2v its also red actually pink(~1.6-1.7vcore it turns red) is it safe to go over 1.56v? do you thinks it needs higher voltages or its to do with ram?
 
If NB stands for Northbridge tried the last possible v. before it gets pink - didnt help.
 
those color changes dont necessairily mean anything. some of them turn colors at the correct voltages, but for example my RAM runs at 2.2v stock. when you set that in bios, its blood red like its very high, although its what it should be. they shouldnt make the numbers turn different colors unless they can do it accurately it will just confuse people.

Hi, yeah Im kinda getting disapointed with commando, - just foundout its not sli and that second pcie slot is 4x. What voltage should I run my ram? 2v or 2.2?

I have an Asus MB also you can adjust the voltage thresholds in PC Prove to reflect what you need the red just means you hit a 10% default threshhold on your voltage just change the4 threshold or the set point in the PC probe configs.
 
Well even if i change thresholds in Probe it still won't matter, just tell me what volts I shouldn't go above.
 
I have my FSB at 1600(400 x 4) so I don't think 1500 is a problem. Im stable too.
 
Ok im clear on FSB now... didnt want to open another thread on this even though the title should be changed.

Is it safe to go up to 1.7vcore or more, and for my RAM what v. should i use - can i try i.e. 2.3-2.4?

What are your temps at 1.7? intel temperature threshold is 68.8C you will dramatically shorten the life of your chip as you increase voltage. I personally would not go above 1.6. You should calculate the MHZ vs. voltage and see if the extra .1 volts is worth the shortened chip life. I use crucial ram and it is stock rated at 2.2 so depending on your ram I would thing 2.3 or 2.4 is fairly safe.

Check out this post on voltage vs. temp:

all depends on your way of removing heat. at 1.7 you will need a phase change or better cooling soloution, even the best water system wouldnt be able to cool it at that voltage. forget about it on air.

no, on the 6600 the thermal shutdown is 85c, and although its debateable around 70c and lower under load is acceptable. i dont usualy like it over 60 but its a personal preference. you can go as high as you want voltage wise as long as temps are controled.

and ram voltage... i dont know what ram you have. look on the sticker it will tell you.
 
1x120 intake 1x120 exhaust 1x90(i think)exhaust side fan(still got space for 1 more), even with 5 fans in total never seen my temps(cpu/mb) go above 40(load). So temps seem to be ok. My ram is 4-4-4-15, when oced(SPD off) 830mhz 5-6-6-15(or 10 in bios). I just want to see how high it can go just for the sake of it... Also itd be nice to get it rock stable at 3700Mhz.., tried running NFS Carbon and it froze after over an hour of playing. What should I do about 5-6-6-15(tried setting em to 4 4 4 15 didnt help)?
 
bump!

Hey all you overclockers out there! plz suggest if it is my DDRII 800mhz thats limiting me from achieving a higher overclock. or if got any ideas than suggest what should i do about my timings(5-6-6-10(15)) - if i set them to something else will it bring my ram MHZ below 800, because it doesnt want to go any higher that 830MHZ(415x9x)?
Plz help me out guys, since i can still get new ram(1k)...
 
what your saying is very confusing. timings dont realy matter, they are more fine tuning then anything. one clock cycle plus or minus doesnt make much difference in core2s.
when you say "830MHZ(415x9x) " whats 830? fsb? is that in 1:1? 415fsb*9multi=3700somthing mhz. your trying to go higher? 75% of people with the e6600 top out around 3.5-3.6 dont be surprised if you cant get more then that.

Im sure I can go higher;).. 830Mhz is my RAM showing up in BIOS when I increase my FSB, but highest I could've went is 830Mhz. (415x9)- ok stability...
Ok look, as I increase the FSB and press enter - my RAM increases also(automatically) in bios(say from 800 to 820mhz etc...).
So I was wondering if I had 1066Mhz RAM -would it allowe me to oc higher then 3.8Ghz?
Thats all... Pardon me 4 my bad English:)

no it wont. you are barely overclocking your ram as it is. you have plenty of room to work with. im guessing the CPU or motherboard is your limiting piece of hardware. your just not going to get it any higher. if you want to make sure drop the multiplier to 7 or 8 and try to find the max of your ram.

Tried dropping it down to 8x and it caused hard lockups(even in BIOS) - took me 2-5mins to return it to standart(stock)...
I never changed the multi to something thats below(even on SD) - used 11x:) and it still oced like bitch:p to 2.86Ghz, and most ppl werent able to get it stable in games passed 27xx(something like that)... so since then i dont trust multipliers
 
400mhz fsb x9 multi =3.600ghz
400mhz fsb x8 multi = 3.200ghz

if your CPU is holding you back, say its limiting you to 3.6, this will let you get a higher FSB while keeping the same CPU speed. this doesnt take your motherboard out of the equation though, that could be the bottleneck.

but as i said, you are dreaming if you think your going higher.
 
I aint really dreaming of going higher, its just that on SD it could go above 2.9 but no where near stable in games(as was at 2.86). It booted into win at almost 3Ghz, but was getting blue screens...
It looks as if nobody knows how to oc their cpus to the max :(

you obviously dont know what the "max" is because you still dont understand why you cant go higher. we are talking about an e6600 core2duo like in your sig right?

what is SD? and where are you getting 2.9? are you talking about a different processor?

before you said you got it to boot around 3.6ghz? then what do you mean by this

and i dont think i asked before, what are your temps under load?

Ok look, my previous cpu was an amd64 SanDiego 3700+ oced to 2.86Ghz - stable in games(over 3-5hours of gameplay) - prolly even more, its just i dont game 24/7 and do not run benches like 3dmark...
I had it in my sig recently, but with C2D.., 3700+ 939 and 3200venice754 - my sig was a bit too long... - saw couple a ppl complaining about other people's sigs being too long, so decided to delete it(just incase i dont pissoff a MOD here), so now i got to explain it every time to ppl who ask me about it - and to be honest its more of an annoynig thing rather than getting help from some1...
I mean if a Moderator doesn't mind, I can put back in my sig, so i dont have 2 explaint to ppl that dont catch my drift on the go(if u know what i mean) - sory 4 poor English...

Now, can u actually suggest something that'll help oc my C2D rig pass 3.8Ghz?

thats all well and good, but it has ABSOLOUTELY NOTHING to do with this except confusing the hell out of me when you all of a sudden start referencing a completly different computer you never mentioned before. any overclock you got on another machine has nothing to do with this one.

more voltage is the only thing that MIGHT get you any higher. temps might be a limit on how much more voltage you can give it as your 'only' on air. your probably close to the limit of what your motherboard can give it too, the settings only go so high (without a voltmod, im not going to explain that one but you can search for it if you feel the need).

its like your driving a car in last gear with the gas petal on the floor and your asking how you can go faster. well the short answer is, as ive been saying- you cant. if your a mechanic and have a very good knowledge of your car you can probably find a way to get a little more out of it. but being, as you said, "a noob at this", your at the end of the line. if you want to get any more out of it you need to learn every single thing you can about your hardware and thru trial and error, reboot after reboot after reboot. no one can give you some magic numbers to plug in to get it going faster. about a year ago i didnt know much about this either. ive built tons computers but i never went for bleeding edge performance like i do with mine. it took months of just going online and reading everything i could find about everything, and then trying it out on my own pc, before i was any good at it.

good guide on RAM terminology, disregard the AMD/system specific information, its a bit outdated

hope that helps, if you still want to go faster you have to figure it out on your own.
