I don't understand why they'd recommend that if it can actually go to 1.45 V without problems. I'm thinking that people are readiong Intel's specs differently and it's causing confusion.


I'm personally doing 2133 MHz CL9-10-9-27 on my kit rated for 1600 MHz CL9-9-9-27 and my CPUIO is 1.05V.
Intel spec says 1.38v for a safe 24/7 overclock. SO anything over is dangerous. Which is why I laugh my socks off at people running at 1.45-1.5v. I think they're insane, or insanely rich.

You realise anything over 1.38v is going to kill your chip?
I agree that his voltages are very high for his OC, but it's not gonna harm his CPU. The max voltage is around 1.45 - 1.5 V.

First of all, we were talking VCCIO, not VCore. Second of all, we're doing everything within Intel spec, it's just that MSI are saying that VCCIO can be way higher than Intel says it can. That's what we're discussing. Please read the posts before spewing BS.

I also find it funny that you're saying we're taking unnecessary risks, but you're using a high BCLK yourself. Oh, the irony.

when i open my MSI CONTROL CENTER AND CLICK THE GREEN POWER, I found out that my Total Power consumption is gradually rising im just browsing the internet, watching youtube.. Total Power Consumption increases slowly up to 800 watts! My power supply is only 750 watts, im just confused even though nothing bad is happening but what does this total power consumption means? when I'm playing games it could reach up to 5000 watts LOL, im just worried that it would overkill my power supply!! Thanks for the Help if any!

*sigh*

Every chip is different and not everyone will get the same overclocks at the same voltage. I'm glad for your friend, he seems to have a better chip, but given how many factors are involved you can't make any assumptions based on that. I really wish people that just jump in and post YOU'RE GOING TO FRY YOUR CHIP OMG! would put up some proof on how exceeding this magical 1.38v is going to cause my little wafer of silicon to go into critical mass. (I even linked the SVID data sheet directly from Intel above showing that max is nowhere near 1.38v. )

This all comes back to what B!ohazard and I were talking about when it comes to people interpreting data instead of knowing concrete fact. Oh, and that screenshot was just for testing C1E with the new BIOS. I'm currently at 4.8Ghz@1.456vcore. (i/o at 1.05 ) Should I grab the fire extinguisher?

D'oh! There goes my hopes of seeing 2133 on an MSI b3 board.
(In before someone says their "friend" has one at 2133Mhz with a 6Ghz CPU )

Well, I could boot at 2133 MHz, but it'd crash shortly after. I've reinstalled Windows yet again because I corrupted it today

I seem to have it stable at 1866 MHz CL9-9-9-27 1T with 1.48 V I think. Pretty decent for a kit rated for 1600 MHz with 1.65 V.

BTW I've got 2 flames now. U JELLY?

lol, I'm jelly. (grats! )

Yeah, 1866 was the highest I could get on my stupid-expensive kit rated at 2200Mhz without any stability issues. That's why I'm back to using a 1600 kit for now.

Hello,

i received my new system yesterday, this is it:

2 x KINGSTON HyperX (4096 mb, 1600 mhz, CL9, 1.65 v, non-ecc, unbuffered)
1 x INTEL Core i5 2500K (3.3 ghz, 6 mb, s1155, 95 watt, boxed)
1 x MSI RADEON HD6970 (880 mhz, 2048 mb, DDR5, 5500 mhz, 256 bit, 11, fan)
1 x POWERCOLOR RADEON HD6970 (880 mhz, 2048 mb, DDR5, 5500 mhz, 256 bit, 11, fan)
1 x OEM Assembling and Configuration
1 x SAMSUNG Spinpoint F3 (1000 gb, sata/300, 7200 rpm, 32 mb, 3.5")
1 x COOLERMASTER CM 690 II (black, no psu, atx)
1 x MICROSOFT Windows 7 Home Premium OEM (64, OEM, NL, SP1)
2 x NEC DVD ReWriter AD-7260S (24x, sata, black)
1 x EDIMAX Wlan Card (300 mbps, pci)
1 x SCYTHE Mugen 2 Rev B SCMG-2100 (s775, sAM2, s478, s939, s754, s940, s1366, sAM3, s1156)
1 x CORSAIR HX (850 watt, atx, sli ready, modular)
1 x MSI P67A-GD65 v3

i ran the basic 3D mark11 en got 8703 points, is that normal? Or is it supposed to be higher?

Also, the physics score was 'only 5500', is that normal for an I5 2500k?? it seems pretty low.

Can anyone please tell me in simple terms how i can safely oc the system for my specific setup? i have never oc'ed a pc before, but these new cpu's seem to be easily oc'able. Help would be greatly appreciated.

I just want a standard oc without much risk!

if anyone could give me some specific bios adjustments, that would be great.

I've seen oc tutorials for this chip, but i'm scared to try it. i don't want to do too much, you know?

B!ohazard has a pretty basic and easy to understand review with some overclocking instructions in his sig. I wanted to post this before him so I could steal his thunder.

UEFI update

First you'll want to flash your UEFI to a recent one.
To flash it, download the latest UEFI version and use this: http://forum-en.msi.com/index.php?topic=108079.0
This tool is safer than the UEFI M-Flash so I recommend this to avoid failed flashes and bricked boards.

At the time of writing (April 1, 2011), there are 2 choices:
Official 1.9 Version or the newest beta 1.10b5. I can't promise that the beta will work for you (I lose keyboard support in the UEFI with 1.10 beta versions), but it might have a fix for a problem you have.

DISCLAIMER: UEFI flashing can lead to bricking of your board. There's a 1/100000 chance that it'll fail and that the motherboard will become useless.

How to overclock manually

Before overclocking, you need the right programs:

CPU-Z - For checking clock speeds and vcore
RealTemp - For temperatures
Prime95 - For stressing


CPU Base Frequency is the BCLK / FSB on these CPU's. Almost all frequencies are tied to this and it must not be changed. Doing so can lead to fried HDD's, SSD's and other bad stuff.

CPU Ratio is the multiplier used for overclocking. FSB / BCLK overclocking isn't possible since nearly all frequencies have been united in one.

”Adjust CPU Ratio in Windows”:
You'll want to disable this feature if overclocking in the UEFI as it'll override you UEFI overclock.
You'll want to enable this feature if overclocking in Windows as it's a requirement for Windows based OC'ing.

D1 CPU's:
Internal PLL Overvoltage has to be disabled.
D2 CPU's:
Internal PLL Overvoltage has to be enabled for 4.8 GHz overclocks and up. With PLL Overvoltage disabled, you'll be able to use up to and including 4.7 GHz.
I've heard that the limit may vary, so some of you may be able to hit higher OC's without ennabling this setting.

Set DRAM Frequency so the RAM runs at it's rated speed.

Disable X.M.P.

Set DRAM timing to linked if you want to enter the timings manually. I believe it can be left on auto, but I'd do it manually.

Spread Spectrum should be disabled for stability.



VDroop Control is supposed to be LLC (a function that eliminates VDroop, allowing better OC's), but it doesn't seem to affect anything. Leave on high. High is supposed to be high VDroop, meaning low/no LLC and low VDroop is supposed to be high/max LLC. Low VDroop Control will give better overclocking, but shorter CPU life when the functions work.

CPU Core Voltage is the voltage you want to change for CPU OC'ing. 1.3V should be more than enough for a 4.5 GHz OC. Intel has a max VID of 1.52V, but that doesn't really help us much since max VID =/= max safe voltage. I'd personally stay under 1.45V and that should be enough for OC's in the 4.8 – 4.9 GHz range.

CPUIO is for RAM overclocking. Keep at 1.05V. Try to stay below 1.08V, but if necessary (RAM instabillity at high frequencies), bump it to 1.15V or something. This setting is irrelevant for CPU OC'ing.

DRAM voltage is what it says, set this to what your RAM is rated for. Intel doesn't recommend voltages over 1.575V, but according to Bit-tech's guide to OC'ing, it's okay up to 1.65V. I'll take the middle ground and say that it's alright up to 1.6V and that 1.6 to 1.65V is largely reserved for benchmark runs. This setting is irrelevant for CPU OC'ing.

System Agent should stay @ 0.925V. Don't go over 0.975V. This setting is irrelevant for CPU OC'ing.

Some sources say that CPU PLL can help stability and some say that it can't. Should be 1.71V < CPU PLL < 1.89V. Some people have actually seen increased stability with lower voltages, so if you're right on the edge of stability, try first lowering and then increasing this voltage.
For D2 stepping CPU's, most will only need to enable Internal PLL Overvoltage. On D1 chips, it can be helpful to use higher PLL voltage because they don't support Internal PLL Overvoltage.

DDR3 VREF and PCH voltages should be left on auto according to Bit-tech. If you decide to tweak the PCH voltage, keep it conservative, the heatsinks aren't built for huge overvoltages. I believe these are irrelevant for CPU OC'ing.


As a final note, I'd like to mention that MSI boards overcompensate the vcore grossly when under load. Expect your load vcore to be 0.02 to 0.04V higher than you set it in BIOS. If anyone finds a fix for this then I'll be very grateful.

Stress testing:

Open CPU-Z to keep an eye on clock speeds and vcore. You want the clock speed to stay at the OC'ed speed, if it decreases while stressing, it's likely that the CPU is overheating.

Open RealTemp (or other similar temp monitoring program) to keep an eye on temps. You'll want to stay under 75C, but I'd say 80C is allowed for a Prime run. It'll most likely never get as hot during gaming.

Open Prime95 and choose Blend (to activate the Blend testing program). Then choose Custom and set "Memory in use" to your amount of RAM minus 1 GB, so if you have 4 GB RAM, you'll want to set it to 3000 MB.

Some people will tell you to run it for 24 hours for maximum stability, but if you want my advice, just run it for an hour and then play games and use the internet for some time. No crashing means you're stable.

Lol

Also, I'll have to rewrite that overclocking guide I've only written about the settings and features I used and new people will want to know what each and every one of them do. I've also started using EIST which requires Power Management which opens up about 5 new settings.

ok, so i just did my first oc

i changed my ram to correct imings, and enable pll overvoltage and just changed the multiplier to 42

http://img842.imageshack.us/i/firstocreport.jpg/

left all the rest alone.

is this ok? everything still fine?
