How do I overclock Crusial Ballistix - Overclock.net

Metalica732 · 08-27-07

Hey guys i'm new to the OC'ing thing and i'm going to be purchasing an E6420 and a gigabyte mobo and a pair of ballistix

and following This Guide

That is the multiplyer for the mem as i understand

The way i understand you get MHZ is by multiplying the Mem multiplyer times the CPU FSB=mem frequency

I'm planning to do a 3.2 ghz OC on the CPU so that is 400FSB and the multiplier will be 8X.

This guide is using chepo corsair value ram so it's not what i want

As I understand those are the timings and to OC you must relax the timeings here are the timings for the ballistix 4-4-4-12 and at 2.2 volts

In that picture what should i tweak to get a looser timing, i think it should be like 5-5-5-12 or something like that. Which option should i tweak

in the guide they do a 2X multiplyer because it's value ram but i will be doing a 3X probably because i don't have crap ram.

So can somebody help me out

well, try to overclock your ram with stock timing first, see if it could handle what you throw at them.. if you do push too hard, then yes, youll have to loosen the timings if you want higher mhz from your ram.

usually, its like: higher ram frequencies = looser timings; lower ram freq = tighter timings..

since youre running 400 front side, you should consider running a ram divider of 2.33 or even 2. running 3 means your ram will be at 1200 mhz

but yeah, try to push everything at stock first, then when you feel youve 'hit a wall,' then up the volt for cpu, ram, nb etc...

I just run mine at 1:1 (400) and tighten the timings. As for the volts, my Ballistix booted up at 400Mhz 4-4-4-12 with 1.8v so you have a nice amount of headway on these.

Crucial Ballistics are capable of running extremely tight timings at incredible speeds..it just depends on the amount of voltage you are set up to deal with for 24/7 use.

Depending on what set you buy [ddr2 667, 800, 1066] you will be able to run a wide range of speeds at pretty much stock timings, by merely adjusting the voltage as the speed increases.

The main thing is to use MemTest or Orthos to rigorously test the RAM for hours after timing or speed adjustments to endure stability...Windows corruption is often a result of bad RAM settings that caused massive errors.
*If you purchase the 800mhz Ballistics, you should have no problem running them well into the 1066mhz range @ ~2.2-2.3v..at cas4 settings [stock timings]. But, remember..speed isnt everything...you could also run 800mhz 2.3v in cas3..and probably end up with a faster rig, due to the latency reduction and the fact that C2D's benefit very little from Mhz increases in RAM speed over 800mhz.

hope that gets you on the right track, good luck and PM if you need more help.

set your ram and FSB to a 1:1 ratio.

set the ram voltage to 2.1v

now the fun begins. as long as you have a good CPU cooler, you should be able to reach 3.3 - 3.4 ghz with that e6420.

set the FSB to 400, which runs ballistix at stock (800mhz). Your E6420 will be running at 3.2ghz at this point. If you are satisfied with this overclock, try to tighten the timings.

You should be able to get at least 4-3-3-6 2T with that ram at 2.1v.

PART 1

Ok now look at this picture. This a screenshot from the bios i will be using

So here is what i understand so far. The stock timings are 4-4-4-12 and at 2.2 volts. So what you guys are saying is gradually up the FSB but i don't understand what Multipliyer should i use 2 or 3. And the goal is to get them to about 1066 or to 1150 or somthing in that range. I understand that these moduals can get to that speed.

The stock speed of the E6420 is 2.13 GHZ i'm planning to take it to 3.12 GHZ with a Tuniq Tower.

So with that i understand is that i will be using a FSB of 390 with an 8X multiplyer which will get me to 3.12 and

a 3X multiplyer on the Ballistix which will get me to 1170 mhz. This is what i want to do. Now i need to know if the ram will hold up to the task or will i have to lower the FSB. If it is not stable what will i have to do

a.Loosen the timings
b.take it from 2.2 until 2.3
c.both

PART 2

If I understand you threw the MAGIC that is PAINT

i created what my bios will look like. Tell me what i did wrong

Where it says DDR2 over voltage control that is where the stock voltage is 2.2 and to OC i will have to do +1000 which will take me to 2.3 if needed.

But first I think i should not mess with the voltage

Here is what i think

1.Boot into Bios
2.OC the CPU to 300FSB that will give me 2.64 GHZ boot into windows and check if everything is OK. "question-will me moving my FSB affect my MEM if the setting is still on auto, as i understand it only affects when i set it to manual"

3.so if everything is ok i stick with the 3.0 multiplier and set the ram to manual so the FSB starts to affect it and gradually when i hit 380FSB i do an OROTHOS for about 2 hours make sure everything is Kosher

4. Since everything is good i go to 385 FSB and do Orothos for another 2 hours

5. Go to 390 i will be sure that CPU is ok so now i have to focus on RAM.

6. if ram is not behaving well like in the picture first should i loosen the timings or should i first up the voltage, probably loosen the timings first i think if timings are loosened and can't do anything then i will up the voltage +.1 which will take me to 2.3 or will it take me to 3.2 ANSWER THIS IS VERY IMPORTANT

then i go an orthos over night and make sure everything is great

Everyone that helps will receive reps+ and i gave you all reps for the help

Well, if you want the Ram to go into 1000+, you should be able to do that at 2.2v or 2.3v but relax the timings a bit. What a lot of people would suggest you do is run it 1:1 with your FSB, and then tighten your timings (try 3-3-3-9 or something around there). So if you want to run your E6420 at 3.2, just set it to 1:1 and your FSB and Ram will be running at 400Mhz. From there you can go for a higher Ram speed or tighten the timings. But these sticks of Ram are rated at 800 4-4-4-12 and 1,000 5-5-5-15, so you shouldn't have a problem getting to 1,000 if you prefer.

If you want to read more into timings vs. clock speeds, this is a great read for that. http://www.tomshardware.com/2006/03/...ies/index.html

thx i will give it a read.

what do you exackly mean by 1:1 and i've looked at these bios screen shots and I don't see anything like that. Look up at the higher up post and tell me if you see it.

hey WAIT you have the same mobo i'm going to be getting and the same ram.

DUDE write up a guide on what you did. that would be alot easier. I'm going to be getting the exact same system as you

What is the diffrence between cpu voltage and vcore. also what is the stock voltage ont eh e6420

cpuv = cpu vcore = cpu voltage...mmk. And stock voltage on cpu's vary...there is only a recommended range of stock voltage, which is typically- 1.1-1.35 or 1.37v. All Intel cpu's have whats called a 'VID'..or 'voltage identifier'. Only it determines the vcore for stock operation. Using a program like 'CoreTemp' you can find out what your cpu's VID is...or you can monitor the vcore in Windows, with the mobo set to 'Auto' for cpu vcore.

Also..you have failed to mention what Crucial set you are purchasing...whether 667, 800, 1000, or 1066mhz...

The 800mhz kit will not run at 1170mhz, unless you are giving it 2.35+ volts..are you prepared to deal with that kind of heat? 1170mhz runs the IC's warm already..2.4v is going to increase the heat dump into your case, raising your ambients...not to mention if the RAM are not cooled properly, they will burn out after a few months...maybe sooner even. As far as over-volting goes..I have never had a set of RAM that burned out from too much voltage...temps have been the only thing to claim them so far. That said...its hard to run 2.4v for daily use using air cooling...air temps fluctuate too much during the day, where I live any how...if you live in an ice box, it should be no problem.

Well, Gigabyte boards don't have ratio's set as 1:1 but in numbers. So if you want your Ram to match your CPU FSB in a 1:1 ratio, set the memory multiplier to 2 (if set to 2.5, that is 2.5:2 - 2.5 being RAM and 2 being the CPU FSB, 3 is 3:2 and so on).

Since running 3.2 is quite easy on my chip, I didn't really have to change all that much in BIOS. Set the FSB to 400, undervolted to 1.325v (stock is 1.35v) and set my Ram multiplier to 2. I played around with the latency a bit but left it at 4-4-4-12 at 1.8v for now.
