I have a AMD 3800+ Manchester dual core (running 1.3 volts) on a MSI 7185 N Force 4 board Rev A3/Bios 6. -1GB Corsair DDR400 value ram at 3.0 cas latency timing 4 4 8 command rate 2T. Zalmen Artic cooler Antic case with added 120mm fans top and bottom and x1800xt with stock cooler. PSU 450 Antic true power. Any headroom here for a overclock? If so what should I look for? Thanks. :?:
The 939 x2's in general are ok at ocing (am2 have been better in my experience, got the 2mb cache version of the 3800 above 3ghz woo hooo!), so expect probably 2.6-2.9 depending on your chip. I think your value ram will be the biggest bottleneck though
truly, anything but value ram. I will say that corsair makes some of the best ddr ram (stay away from their ddr2 for a while though). So get 2gigs of their platinum cas2 sticks (price is actually less than their regular cas2) and that should be plenty for what you want.
You always could simply lower the divider, but you would get probably less performance anyways because of the timings, as the less mhz won't make as much of a difference as the timings, and you always want to keep the 1:1
But I have to say, not 3ghz with a manchester, maybe the newer windsor cores, I have found them to be much better in general, going to at least 3ghz in general while I have seen manchester 4800's hitting a wall at 2,9ghz or so, and the 4800 beats the pants off a 3800 when compared at stock because of the higher mult and more cache
Missed the manchester part. Yeah, I had a couple Manchester cores which clocked as high as 2.65 and 2.7ghz. So, once again, sorry about the misinformation. The newer cores can reach 3ghz, but you would have to have a 1 in a Million to get a manchester that high.
Well the Devil is in the Details I will check the stickies fo instructions but from what you have said I will probley see more results by OC the X1800XT graphics card. :roll: Thanks for the input. I built this rig (first build) when the 3800 first came out and now I'm getting antsey to try my hand at something else.
zalman or arctic cooling (two seperate companies) I would say from personal experience to stay away form zalman, but that's just my experience with them. So far they have turned out to be way too expensive for the price and I don't think they are worth it no matter how many lights and fancy designs zalman incorporates until they offer something that can beat a scythe infinity/ninja or tuniq tower that doesn't cost $80 like the 9700
Well it's the Zalman 7000B. I had room for it with the Antic Sonata case. It had good reviews,was 25.00 US on sale and has brought temps down by 10deg. So I guess I have been happy with it but it was my first build like I said so I don't have near the experiance of the rest of you. I will check out those brands you mentioned in the future. Thanks
I learned all that I know from taking the same steps you did. I simply bought parts I thought were good until I learned which brands actually give the performance for the price and by coming to toms, don't worry, you'll catch up to us, you seem like a smart person
Well, I have the 4000 windsor (same thing has 3800 with twice the cahce) and my mobo is the crosshair. Depending on when you got your ram, I think you should be able to hit fx-62 speeds of 2.8 or so. My mobo is a bit better than yours and I hit recently hit 3.05ghz with air cooling, but I also have a different kind of ram. If you bought your ram mid-novermber or earlier, I think that your ram should not be a bottleneck until your mobo becomes one. Otherwise, just set the ram to ddr-667 or ddr-400 for the 1:1 (actually 10:10) ratio and I think you should be fine with stock vcore ro up to 1.375 at most. The windsor core has proven to be more oc friendly than any of the 939 cores, but still not good enough to match the conroe/allendale core due to the arch. So if you have worthwhile cooling, expect 2.8 or so, because I think your mobo might be your biggest bottleneck, otherwise people have gotten the 3800 to 3ghz with some very nice cooling (perferrably water)
Thanks for the quick reply. I wonder what is up with the date of the Ram purchaes? I purchased it about two weeks ago. So that might make a difference? So you think that I should keep vcore at about 1.35 and then just up the ht until I max out. Once that heppens add a divider to my memory, i,e, 667 mhz, and then continue on? Do you see a need for changing the processor ratio?
no problem. The reason why I ask is because ever since Novermber 28th corsair officially switched to promos IC (yes, I know its sucks, I originally bought some corsair dominator but when I tried ocing it I immedietly rma'd it for some super talent). Ohh well, that won't stop us. Just lower the ht to 4, set the ram divider at ddr667 like you said (ddr400 would be perferrable though, because the 10:6 ratio is an offset ratio and 2:1 and 1:1 aren't) and tighten the timings to cas3. You may have to raise the voltage on the ram to something like 2.3 and you should be fine. Maybe set the vcore at 1.375 though, but mine gets to 2.9ghz with stock vcore
