Little lower....
post #912 of 5036
You could probably increase the NB to about 1.25 or so and overclock the NB to about 27-2800MHz. But if you cannot separately adjust the HT frequency on your motherboard then keep it down to about 2500.

Increase the FSB and see what happens?

If it's not stable then you need to decrease the NB or HT, or give cpu more voltage.

Trial and error....you aren't likely to hurt the cpu trying to overclock it.

My specs are bellow and im running at 3.5ghz per core..

These are my Voltages:
DDR3 Voltage: 1.6
NB Voltage: 1.1 (Sits on 1.1500v in everest) is this ok?
SB Voltage: 1.2
CPU NB VID: 1.5
CPU VCORE: 1.4250

HT: 2000mhz (stock)
CPU NB: 2000mhz (stock)
RAM: 1332mhz
Clock: 250*14 3500mhz per core

I have had a read of the guides and it seems all good but could someone just reasure that everything is good

Thanks

Ok i have overclocked to 3.7ghz per core and pushed the HT and CPU NB up to 2200mhz.. also i increased CPU NB voltage to 1.2v. I am not prepared to go beyond 3.7ghz without proper cooling lol Anyway prime95 is running now.. i will post the results

Ok well it looks like 3.5ghz is the max for me until i get decent cooling.. Prime95 came back with loads of errors at 3.7ghz and also tempratures hit 65-70 within the first 5m... Anyway 3.5ghz seems to work well and prime95 reports no errors

That's hot. You definitely need to upgrade your cooling system.

Yeah lol... Im typing up a document now and sitting on about 30... not too bad I was thinking of purchasing the Corsair H50 (water cooling).

Hrm I posted this in another thread but it seems more prevalent here:

Hello peoples with X6's. I just got mine yesterday(1055T). I don't have a top end board but it's been really good to me so far (M4A78T-E). Anyways...

I'm a little stumped. I can post at 4Ghz but that's not what I'm even aiming for. I'm really looking to make my first 1Ghz OC. I can post at 272*14 at almost any voltage, but it's taking like nearly 1.5v just to load into Windows.

I'm debating the idea that it's a borked Windows install (hasn't been reinstalled for almost a year now), or my chip just really needs a lot of volts with this board. I see a lot of people with this chip and the 1090T at similar speeds around 1.4~1.45 and even less....

And that's not even stable... 229x14 stable no problem but I'm shooting higher~




EDIT: I also get a weird message every other boot or so 'CPU Fan Error!'... really odd.

If you look at post #1.....you can see the average for 4.0-4.06GHz is 1.528v

EDIT: and if you added my 1.5v for 4GHz it comes out to 1.526.

EDIT: new stable overclock here....4242 MHz!

FSB/Multiplier:303x14
CPU Speed:4242MHz
NB Speed:2727MHz
CPU Voltage:1.57v
CPU-NB Voltage:1.31v
RAM Speed:1616MHz
Motherboard:ASUS Crosshair IV Formula

IBT

prime blend (I had to cut it short...4 hours and 4 minutes...have to go to work)

CPU-Z anyone?

help on OCing

Here is what I have so far.



Prime95 for 8+ hours. I feel like this is fully stable.
Result is
fsb = 265
HT, NB multiplier = x8
FSBRAM = 3:8

I had some problem posting at FSB = 270 with stock voltage before I got the result above.

Questions:

1. does running ram speed lower than their specification hurt my performance much?

2. Am I doing okay in OCing? What can I do better? Stability is more important to me. Is this a good place to stop?

Your CPU NB VID and CPU VCore look a bit high, depending if you have turbo core enabled or not. The NB VID is mostly needed in my experience if you OC the HT links - I can do 3.9 GHz (with turbo off) at stock NB VID, so +0.025 or +0.05 should be sufficent unless you OC the HT links by large margin.

Now CPU VCORE at 1.425 should be quite safe as long as you have turbo core off. If you have turbo core on then when it OC's your three cores it adds +0.1 V overvolt to those cores and you would end up with 1.525 V on those cores. This should not cause (propably) permanent damage but should not be needed for 3.5 GHz.

When playing around I found 3.5 GHz to be rather sweet spot for mild OC at low volts with turbo left on. It was stable at stock volts on CPU (1.375 base and 1.475 with turbo) and mild bump on NB VID (I OC'd it up to 2500 tho). That way I had 3.5 GHz base on all cores and turbo was able to push up to three cores up to 4.125 GHz when needed.
