Newbies first OC a sucess!!!

[imperfectcircle25]

I am new to OC'ing and this was my first attempt. I got my 3800x2 to run 2.5ghz stable and cool

I have it setup as follows
cpu 1.45v
10x250mhz
HT x 4
250mhz 3-3-3-8-1t 2.8v

Not bad for my first shot, thats 4800X2 performance! Nice to know you can take a $300 cpu and get it to perform as well as $600 one with a few easy changes to the bios. I just need some decent cooling and Ill be fine. Whats the safe voltage and temp range for the 3800x2?? I dont wanna push it to hard, i just wanted to see what it was capable of on air I will probably run it 2.4ghz so I dont push it to hard esecially with the small cooler I have currentl(gigabyte ghed-821). Im thinking of water cooling, more for the quietness than for the OC abilitys. Whats about the fastest these 3800x2's are running??
thanks

congrats!

Thanks
Whats the fastest these dual cores can run on air?? I was surprised I got my 3800x2 to 2.5ghz so easily. A 500mhz overclock on the first try is not bad. The dual cores are great!!! What is the best 2x1gig memory kits available now?? My OCZ gold isnt to bad but ive read there are some 1gig sticks with tighter timings available now?
Thanks

Try and go higher! Shoot for 2.7!

 

[Centoros]

That's a good clock man. I believe your probably about as high as your gonna go with it. Most 3800s I've seen hit the 2.4 - 2.6 range with some being higher. As long as it's rock solid and stable, you've got a very good clock going there. Nice job

if u get lucky u could get a chip which i got (paid 50 bucks more got it from a local shop ) and it hits 2.7ghz stock voltage, well set to 1.375 to counter the voltage droop.
But it just up to luck to get a good overclocking one, my boss got a 3800+ x2 and it only goes up to 2.4ghz on 1.4 volts in bios, anymore and core 1 craps out.
By the way nice overclock, can u run it with less voltage?

 

[imperfectcircle25]

I brought it down to 2.4ghz for everyday use and it runs cool and rock stable at 1.4v, Im gonna see if it will run at 1.375v. Opps i forgot to change my signature. I swapped the 4 sticks of HyperX with 2x1gig OCZ gold pc4000.

Congrats on the overclock, but I'm afraid that's a bit optomistic speed forcast. Smaller L2 cache reduces 3800's performance at similar clocks. Might even cost you another $300 or more to set up the right cooler, do the sums carefully, you might be better off to have bought the 4800 out of the box. Also much less risky.

The cache makes almost NO difference unless you're running a server app (or something along those lines). Only thing it really accomplishes for most of us is increase heat output

Watercooling can be as cheap as 100 (GAG!) and as expensive as 2000 (Yes, someone did it at XS). Usually the 225-300 dollar range is ideal.

Also Mhahnheuser, you can't look at a water system as a one time thing. Odds are in favor of the components lasting 5+ years provided they are quality ones. So, it'll last him for this setup... and the next... and the next.
And he'll be able to cool his video card, as well.

Are you forgetting the much higher memory bandwidth he's getting with his overclocked memory as well? I'd take the 25% faster memory clock + 100mhz more cpu speed any day. He'll be faster than a stock 4800 in just about every benchmark.

Oh and to the OP, nice overclock:thumbsup:
You might consider this list of air coolers before jumping to water (unless you just really want too). Those are numbers from a 4G prescott. Your cpu will be much cooler... With the help of a utility like RMclock, you can get pretty quiet with good air cooling. For what its worth, I'd be very leary about any $100 water cooling setup.

But aren't the cooler mounts on the 940's changing, making it a little harder to reuse items like the afore mentioned cooler? I think Tom's and here on Anand Tech I've read something about it not making those who have invested in these options particularly happy. As for the cache I am aware that the shorter pipelines and memory controller minimise the impact, but if you have two cores that need charging, or one core going flat out, the cache does help in getting info to the core. The comparisons between OC 3800's and 4800's i've seen show the OC 3800 lagging the 4800 in most benchmarks. Mind you there still good numbers, but not quite at 4800+. Doesn't mean he hasn't got value out of it, but if you add the price for a quality water cooler, which you should, I don't think you are too far in front over a 4800 if at all. The GPU sub system will come into this equation to, as both CPU's can max out some pretty hefty GPU's. Just my experience in OCing has not yeilded big returns, and have always reverted back to stock. Very rarely these days does OCing make the diff between playable and unplayable frame rates, especially with these CPU's in the socket.

Is it worth the effort? Have a look at these benches for various CPU's and make up your own mind. Just can't see Manchester out performing Torledo at the same clock speed given that the faster Manchester 4200+ is still well short of the 4800????

I wasnt arguing that it will run exactly as fast as a 4800x2 or anything, just saying its pretty close and for half the price. I have it running at 2.4ghz for everyday use @ 1.375v and it runs nice and col 32c under basic webbrowsing and listening to mp3's and under a stress test both cores at 100% it gets up to around 57c. And thats with a $15 Gigabyte hsf and one exhaust fan on the case. Ok so maybe its a small risk, but im running the cpu at pretty low voltages 1.375v. In the real world do you really think your gonna notice the differance in perfformance between a stock 4300x2 and my OC'd 3800x2?? I am thinking about sme better cooling, but more for less noise the better cooling is basically a nice bonus.

If I had $650 to spend i would have got a 4800x2, but i wanted a dual core because I do alot of mp3 encoding and ripping and to be able to do it in the backroud wthout slowing the cpu down at all was worth the price to me. The 3800x2 actually replaced a single core 3800 which at the tme i wasnt to sure about since I gave up 400mhz in clock speed to the single core. And I was right, in single apps the single core was faster. thats when I descided to OC the X2. i wanted it to be at least as fast as the singlecore 3800 in single apps but be much better at multitasking. So I did some experimenting with the 3800x2 and got it to run at 2.5ghz rock stable and it made a significant differance in real world performance. I descided to run it a bit slower at 2.4 so I wasnt pushing it to hard for everyday use, and i am very happy with the chip. So imo OC'ing is a great way to get more performance from your system, and it isnt that risky if you dont push the chip to hard and keep it cool. And even if im not quite at 4800x2 performance im at least at 4600x2 performance for at least $200 less. Not bad for my first dual-core OC!

Wow, gratz on the OC. I'm trying my hand in it as well (atleast seriously) for the first time.

Anyone have any tips as to how I can crank a few more mhz out of my cpu and ram? anything higher seems to crash and the 8x multiplier seems to want ubber voltage. 9x, so far, is the most stable and easiest on the volts.

 

[imperfectcircle25]

Heres a few ideas Palindrone
1. set your command rate to 1t for better performance
2. Make sur your HT is set to 4x not 5x
3. Use only the sata ports closest to the cpu the other 2 arent locked

 

[palindrome]

I had my HT set for 3x (3x280 is 880, while 4x280 is 1120) can I do 4x?
benchy bench
I seem to beat out the 3800+ with my crappy ol' newcastle on every test =)
Although I'm happy about this, I still want a bit more from my cpu (though my boot time is incredibly faster). I have an opty 165 retail ordered from monarchcomputer with that insane coupon. I'm still tweaking this proc, so I'm not sure if I'll keep it yet.

 

[imperfectcircle25]

I donno if you can do 4x, but I have mine set 4x and it runs fine but im running 10x250 so 4x250=1000 which is fine. 280x4 maybe to high but you never know. I have a 4200x2 and 3800x2 for sale if your interested. Good luck

Wow seeing so many pple havinf successes in x2 3800+ OC..... think i might try it out.
btw juz bought by x2 3800 recently......can any kind soul advice on how to acheive a 2.4ghz OC on my rig and the steps to do it. Thanks a lot. =)
The mem divider thing juz confuses me alot......LDT? cpu multi ?

[gotfrag]

All I did to get my 2.4ghz is I bought the G.Skill DDR500 ram and just upped the fsb to 240 and I got a nice little OC.
It is also on stock vcore and cooling!
