Never overclocked before but would like to push this baby to it's limits. I have a nice Zalman CPU Fan+Heatsink so I'm not really worried about it overheating. ANyone want to take me through the steps?

Step 1.) Enter the bios :p 

Step 2.) ??

Specs are as follows if it helps:

CPU: Athlon x2 245 Regor 2.9ghz
RAM: Wintec Amp-x 2x1gb DDR2 1066
Motherboard: ECS Black Series GF8200A

Best solution

Hey Bear,

I just decided to overclock a budget build that I did about three weeks ago. I am still new at this, this is only my second overclock. Here's a screen shot of my moderate overclock for 24/7.



I posted on an earlier thread asking about a 240 regor. Seems that some have gone as high as 3.7, so there is some head room. As you can see my temps are good. I used stock voltage (1.35) and lowered the ram multiplier so as not to overclock my ram. I don't feel confident enough to give you advice, as I am new to this as well. The community was very helpful. You will probally get some replys that are familiar with your bios for specific advice for settings. Read the "Sticky's"on the the main overclocking page, that's the best place to start after reading your MB user guide.

System as follows

AMD Athlon II X2 245 Regor @3.480 (240X14.5) stock voltage
AC Alpine 64 heatsink
Gigabyte GA-MA785G-UD3H
8GB (4x2) OCZ Blade DDR2 6400 2.0v 3:5 ratio 800 mhz 4-4-4-15
WD Black 500 GB 7200 SATA
WD Black 1 TB 7200 SATA
Avermedia Hybrid h788 TV tuner
BFG 8800 GT OC2 (I forgot to increase the fan 61c :o  )
CM Storm Scout Case

Edit"

As I said I am a noob. After looking hard at my monitoring software, I noticed that my HT Freq was at 2400 mhz.... found this"

Quote Xaira
"there was a test done, i dont have a link, but they levied the ht freq from 200mhz to 1000mhz, there was no difference in performance, i was skeptical, still am, so dont drop ur htt to 200mhz, just decrease the multi by however much is necessary to keep it as near to 2000mhz as possible"

I need to make this adjustment.

I've got my 240 cranked up to 3.7Ghz right now. It has been benched for 24 hours with BOINC, and is stable. Mobo Voltage is set to auto. These chips are badazz!.

Highest I can get my 240 to was 3.5 and have it run stable. I don't have the best mobo for overclocking either though. It is fairly limiting on what I can adjust.

guys I'v got a

amd 240
kingston 2x1gb
ASUS M4A78 770
corsair 400W

I plan on overclockin the chip so i got couple questions

1) Did you guys sue amd overdrive?? or did it straight in the bios?

2) do you think my ok to oc my chip to 3.5?

3) What did you guys raise to reach your overclocks

I used bios to overclock, I haven't had good luck with OS based OC tools. Based on my temps I think that 3.5 is reasonable. I raised my base clock, lowered my HT multiplier and changed my memory multipier ratio. Stock vcore voltage. I am stable and cool at 3.480. (see screen shot above, the only change is HT)

Im new to ocing so tell me if i understand everything? you raised base clock(HT bus) to get your cpu running at 3.5ghz which also effected in the LDT being highes so you lowered ht multipier to get LDT back to when HT bus was defult. But im not sure what the memory multipier ratio does?

I appologize, I am a noob too. The problem is that we have two different motherboards and manufacturers, my bios and settings will not be exactly the same as yours. Here is the change I made to my bios settings:

CPU Host Clock Control [Manual]
CPU Frequency [240]
HT Link Frequency [1.6]
Set Memory Clock [Manual]
Memory Clock [x3.33]

These are the only settings I have changed. I chose these settings based on the easy"Math", for the multipliers and the fact that I was only wanting a moderate 24/7 overclock. (about 15%).

I am still quite new to overclocking and not the best to help you, hope this helps a little.

Here is a screen shot of current settings



The only changes I have made is the HT link, and I added an old 7300 GT to have 3 monitors on this system. The monitoring software is CPUID, CPU-Z, CPUID, Hardware monitor, and Real Temp.

k i think i get it i got one question tho when it says memory clock: x3.33 is that the samething as a 1:3.3 ratio HT bus/DRAM??

I'm not sure, like I said we have different MB and bios. I have never owned a ASUS AMD board. your memory clock ratiio should be 3:5.

Yup i I anwered my own question, I dont wanna bribe but Im pretty good at maths so i figuered it out. Thaks anyway.

ill try to explain

IN cpu-z it says for example

RAM:400mhz
HT BUS:D RAM 1:2
the 400mhz is for 1 memory stick so if u multipy that by 2 memory sticks you get 800mhz


On the other hand in the bios it says


Memory clock: x4.00 800mhz The 800mhz is for 2 memory sticks
so if we just talk about one memory stick it would be x2.00 400mhz which is equivalant to 1:2 ratio in CPu-z

So this proves that ratio of 1:2, HT bus:D RAM in cpu-z is same as memory clock of x4 in BIOS
correct me if om wrong someone

Hi, I saw some ocs of the Athlon II X2 245, but... I have the BE.
Anyone knows what multiplier can I put without bumping voltage?

I need to make this adjustment.at the start up menu press delete to open the bios go to frequensy control take your 200mhz to 235 mhz there u go 3.3ghz sweet well thats what happened on my chip same as urs------------------------------

New to Overclocking but not new to hardware.

I have the Athlon II X2 245 with the GA-MA785G-UD3H Gigabyte motherboard with 4gig of OCZ Platinum DDR2 1066.

Here is my CPU-Z validation http://valid.canardpc.com/show_oc.php?id=1120601

Any ideas where I should start and what settings to put?

I have since upgraded to the 955 BE, but if I remember right, it was easy peazy. I set CPU Freq to 240, left CPU voltage on Auto and adjusted the HT freq ratio to as close as I could to 2000 mhz, I think it was 1.6 if I remember right. I think I ended up with HT link freq of 1907 mhz.

I apologize, but it has been a while, and I wasn't trying to max this one out. I knew I was going to upgrade soon, but my wife didn't.

I hope you have an aftermarket cooler, but if not, just watch your CPU temps in your stability test, a 60c ceiling is what I go by. My 245 Regor ran stone cold.

If you check out my screen shot at the top you will see that I am just learning as well. 3.480 Ghz is a nice moderate overclock.

If you are looking for more, it's going to get more involved.

This is not by any means the proper way to overclock. but if you want a quick answer, that's exactly how I did mine.

There's "stickys" at the top of the forum, that's the best place to start.

Sorry Bryan, I forgot you need to clock down your memory. Set memory clock to manual, and set memory clock to 3.33

my bad. sry :sleep:

Thanks Henry. Pulled me up to 3.48 easily. Now to check the temps under load. :)

Cool, you might want to dial back you CPU voltage with manual settings if you want to fuss with it, if you're happy with 3.5 ish. That should help the thermal production.

I really didn't dial mine in as it was temporary. I dialed my CPU voltage back on the 955 BE until instability, but with the unlocked multiplier it made it much easier.

If things go awry, give me a shout, I have an "extra" 245 Regor collectin' dust. I'll send it to you.

Well after much testing and staring blankly at the temperature gauges I have come to the conclusion that reliably my little dualie will run at 3.55 with a core voltage at 1.424. I'm idling around 32-35C and maxing it with OCCTPT we get up around 58C. According to the AMD specs they say this little one maxes out at 70C so I'm comfortable with that. :)  Now on to see if I can up my ram speed.

Henry,

Thanks for the offer. I have a Zotac AM3 mobo sitting around here with a dead display adapter if you wanna trade for that dusty Regor. ;)

hey Bryan , that's an excellent result for a Regor core, I had a 240 and I couldnt go much over 3.3 without having to raise the volts , which personally I don't like doing too much, they are very good chips for the money
