This is my computer's spec Intel Extreme series DP45Sg motherboard Q6600 CPU 2.4Ghz 2GB DDR3 1333Mhz HIS 4650 512MB I am a new guy to computer overclocking. I watched a few videos on youtube about overclocking. I entered the BIOS in the motherboard and this is what i did. *i kept the CPU clock ratio to 9X *Changed the CPU host multiplier from 266 onwards. Then i checked the CPU info from the motherboard and it showed the speeds as 2.5Ghz, 2.7Ghz, 2.9Ghz... as i kept increasing the CPU host multiplier. But the temp didnt change. Even at stock speeds it was about 54C and after changing the above settings they never went above 57C. Why? (Im using the stock cooler that came with the CPU) Am i doing something wrong? If so how to overclock it the proper way?
ah crap, the forum wiped my reply! OK, lets go again. Probably because you haven't shown the cpu any strain or as we say 'load'. Download an appplication called "prime95" and run the small fft test, watch those temps! Also download "coretemp" so you can keep an eye on the temps from within windows.
I would NOT risk stock-cooler overclocking on a Quad. Any temps above 80 degrees for prolonged periods could start playing havoc with the internals. Best way to go about it (imho): Start at 270x9 - 2.43GHz is hardly a record-breaker, but it shows the chip CAN be overclocked, and puts you on a nice round number. Run Prime95's SmallFFT torture test (although I usually change the time per test from 15 to 10 minutes), using Coretemp or HWMonitor to keep an eye on temperatures. Speedfan has a really nice graph for temperatures, but it has this annoying problem of understating quad-core temps by 15 degrees. I use it purely for the graph, to show how temps have been rising, alongside HWMonitor. Let it run until temps stabilise, note the max temps, dive back in to the BIOS, and keep jumping in increments of 10MHz: 280x9 - 2.52GHz 290x9 - 2.61GHz 300x9 - 2.7GHz After a while, you'll start getting bluescreens. With the stock cooler, I'd stop there, but with a good aftermarket cooler, you'd increase the voltage a little and keep going. If you can't get (for example) 320x9 stable, drop down to 315x9. If that's stable, start climbing up in increments of 1MHz (316, 317 etc). If not, start going down until you get stability (314, 313, etc). Other points to note: Leave your RAM at 1:1. This means it won't get in the way of the overclock - if, for example, you were testing 300x9, and your RAM was rated at 800MHz DDR2, 1:1 would keep it at 600MHz. 3:2 would push it to 900MHz, and might cause instability. Turn off anything power-saving (C1E support, etc), as well as Spread Spectrum. Your motherboard manual should go in to better detail. Turn up all the fans in your case, and on your processor cooler, if you want the max overclock for your setup. If that's too loud for you, set them at acceptable levels, but be aware it may limit you by virtue of temps. Use a good PSU! What other hardware (namely case, PSU, and RAM) are you using?
For big overclocks, you'll have to increase it, but again, I wouldn't advise you do without an aftermarket cooler. The Intel stock cooler cannot cope with increased voltages. Start increasing FSB up to the point where the processor fails the stress test, THEN increase to voltage a little (0.0125V at a time). Sometimes you may need to increase the voltage more than once to get to a certain FSB. Don't rush it, though - increasing the voltage too much can cause problems. And again, to clarify, don't increase the voltages if you're only using the stock cooler. You will damage your processor much easier if you do. I think the Q6600 had a max VID of 1.325V, so this is the maximum Intel would spec with the stock cooler, and they were right to - it's pants.
Don't use the stock cooler to overclock, If you don't want to spend much try a freezer 7 or similar. As has been said before just tweak it a little bit at a time & most Q6600's will hit 3.0ghz very easily. I run my Q6600 at 3.6ghz (1.375v) 24/7 with a TRUE bolted onto it. Works a treat. Please chuck that stock cooler in the bin 57 degrees unloaded is quite high, I run overclocked in prime95 at about 65 with all cores fully loaded.
Thx guys. then ill upgrade to aan Aftermarket cooler. If i upgrade to an Aftermarket cooler will this happen. When i OC the computer and even if the temperatures are normal (>65C) will it damage the CPU? I also have a question about the Vcore Voltages. How do i know that the Vcore voltages are too much for the CPU? Will the CPU show Temp increasements?
With a good cooler, you can comfortably head up to 1.4V and beyond. The buzz from everyone else is for the Titan Fenrir, so that might be the way to go in terms of cooling. Overclocking can shorten the life of components. The good news, though, is that if you're careful, it won't have a major effect, and it'll still last for years and years. What case, RAM, and PSU are you using?
At present im running the CPU at 3.00 Ghz (9*344). Then i incresed it a little to 3.10Ghz. Then it doesnt POST. When i try to start the computer it says "Unsuccessful POST attemps detected." I checked the temps. Even they seem to be alright. Then what can be the problem?
And im not using a case at the moment. RAM - Kingston 2GB 1333Mhz PSU - Delux 450W (I know its not a very good brand)
Make sure your RAM is set to the right voltages/timings. If you'd been specific on model number etc, we could have helped you with that. Make sure you're using the right divider too - at 344MHz FSB, your RAM could be trying to run at 1376MHz. If you're struggling to POST, and the temps are OK (under 80 degrees after stress-testing), then increase the voltage, bearing in mind what has already been said about this before (ie don't do it without a good cooler).
This is the info about the RAM u asked for I have 2 sticks of them. Each one is Kingston 1GB DDR3 1333Mhz. I have these on the label The model no is KVR1333D3N9/1G 1GB PC3-10600 CL9 240-pin DIMM And will increasing the voltages overclock the CPU or should i do the OCing with the Host multiplier and host clock frequency?
The voltage increase won't magically overclock your processor. You'll still have to tweak the FSB. For example, you're stuck at 300x9 - 2.7GHz. You can't get to 310x9 at all. If your default voltage is 1.3125V, then increase it in increments of one. Some motherboards will have this as 1.31875V, others as 1.325V. Try again with 310x9. If it's still not working, try increasing the voltage by another increment. Now, I checked up on the RAM - it's designed to work at 1.5V, so make sure that's set in the BIOS. Make sure it's not going over 1333MHz in the BIOS - set it to its lowest speed for the moment, so it doesn't interfere with the overclock.
I also checked my BIOS again . The Max CPU clock ratio is 9x. And the Max CPU host frequency is 500. Then the max speed i can get is only 4.5Ghz Does this mean that i cant go beyond that? Just wondering. I have seen some videos on youtube where ppl go beyond 5Ghz, 5.5Ghz etcc. how do they do this?
That may be the max for your board, I'm not familiar with that particular one. Mine can get around 520 before the chipset and VRMs need watercooling.
I was able to overclock my system to 3.1, 3.2Ghz. But after booting to windows it tends to get stuck. This happened several times so i downclocked to my stock speeds. Why does this happen? And what are these Vcore voltages, MCH/ICH voltages? Should i increase them if im overclocking? And can i use softwares to overclock beyond 4.5Ghz?
You will not get your Q6600 anywhere beyond about 3.6GHz, unless you're ridiculously lucky, and have a water-cooling system. Read this.
