AM2 FX62 Overclocking Action!

**Absolute_0** · 05-23-2006, 08:08 AM

AFAIK all the FX60/62 are coldbugged to roughly the same degree.
3.64 Ghz STABLE is pretty damn impressive OPP, but i really think it needs more HTT to take advantage of the DDR2, although i'm not very sure of the HTT: DDR2 ratio and how exactly it works in AM2. Just a shame teh coldbug prevents high HTT.

lmao^^^ my memory controller is a single channel, and can't go high htt with 2 sticks and it is in this scenario that i know of too well, that i say it IS the imc. htt is issue, not ram speed 'nuff said.

Nice job on the mounting bracket Opp!

I have to figuer out some new mounting for a waterblock I have here and then I can really play with the setup.
I just havn't gotten around to it.

Do you know if the Swiftech Storm will fit?

**Deathspawner** · 05-23-2006, 09:38 AM

Sweet OC! Too bad it's cold bugged

Yea they worked out pretty good.
I was just thinking, the backets I made should bolt right onto this water block. I'll go by Swiftech tomorrow and pick one up.

No it won't, Swiftech is makeing new mounting brackets for the block.

Looks like the theory of the second to last 2 letters being the memory controller is wrong.. how can it be the mem controller when we see a BY chip here, with a completely new DDR2 controller?

**Kunaak** · 05-23-2006, 10:53 AM

hurry up and go for some 1:1 DDR2 overclocking.
no HTT and all that, lets see some big bandwidth, see if 450+ at 1:1 really pushes some bandwidth (even theoretical, it's fun to see new records)

**Steven** · 05-23-2006, 10:56 AM

Why am I seeing all these AM2 CPU-z screenies of cpu's with a 200mhz HTT? I thought AM2 was going to have like a 400mhz HTT. Maybe I'm imagining things, but I coulda sworn I heard it was going to run DDR2-800 at 1:1.

**~~GoThr3k~~** · 05-23-2006, 11:27 AM

and what is frequency of DDR2-800??
rigth, 200

**Mankz_91** · 05-23-2006, 11:34 AM

nice....

Its still buggs be why AM2 costs so much more, all it has is a new memory contoller and an extra pin.....

still, i would love to see some scores of a low end chip, like a semperon 3800or something.

how do you figure it costs so much more?

the Opteron 170 is $400.
the X2 4000 AM2 is $330. same speed, came cache.

the 3800 AM2, costs almost exactly the same as the 939 3800 X2...

across the board, the prices are either identical, or lower then I expected.
FX60 = 1100 a week or so ago.
FX62 = 1039 today...

maybe you need to shop somewhere new.
the prices I saw, were all at Monarch computers.

Thats correct but CPUz has not compensated for DDR2 yet therfor it is 400.

Quoted for truth.

I have the same board here with an FX62, I have not run over 280HTT as of yet, i tried 300, 350, 400 all a none boot, maybe there is some tweak im missing.

Also, im finding 2t settings while making huge bandwidth and high ram clock speeds are not giving the best 3d benches for me, i can beat 1100ddr 4-4-4 with 3-3-3 at 700ish 1T in 3d01...seems latency is still king over masses of bandwidth with AM2.

I have some 7200 EPP OCZ here, i think OPP has the same also, it clocks quite well at low latency with the SLI memory option turned off.

To give you an idea of the bandwidth i have seen, when Sandra 2007 would work i had 5600MB/s unbuffered with 3500MB/s in memtest86, so god knows what i had when i hit 4100 in memtest if i had run a sandra bench..LOL.

I just wish i had 7900GTX's here to run some sli action, all i have is ATI cards at this time.

PC3200 DDR1 is enough to keep the A64 bandwidth happy

review is coming from madshrimps.be in a few days 3500+ am2

also already a nice link for the air cooling guys...heatsink compatibility list

**jmke** · 05-24-2006, 04:02 AM

don't expect miracles from DDR2, and we're not going to try and mimmick the 1000 other hardware reviews out there. Some general benchmark and some more unconvential tests, still brainstorming on that last bit; Friday is AM2 benchmark day

if you look at X-Bit labs DDR1 vs DDR2 comparo you'll see that you need DDR2 800 ram at lowest timings (CL4) to match performance of DDR1 at CL2 2-2-2.
http://www.xbitlabs.com/articles/cpu...et-am2_11.html

we'll have DDR2 667 sticks, timings yet unknown

**Mankz_91** · 05-24-2006, 04:12 AM

here, in the UK from www.scan.co.uk-

X2 3800 (939) = £192
X2 4400 (939) = £299
X2 FX-60 (939) = £587

X2 3800 (AM2) = £ 213
X2 4400 (AM2) = £ 330
X2 FX-62 (AM2) = £ 720

So bar the FX-62, we are paying some £20ish premium for DDR-2 support and an extra pin.

i know that DDR-2 merits faster speed ( when running @ 1000 mhz) , but im happy with the speed of my
X2 4400 (@ 2.35 on stock cooler @ 1.35v) with 1Gb of PC-3200 ATM (3-3-3-8 @ 210), it beats my mates Wc'ed P4 EE (3.73) and it cost like half as much, so i see no need to upgrade unless, there is a huge leap in performance. ATM the thing i like the most is the nVidia 590 SLI chipset and thats it.

Hmm thats cool! I've been overclocking my PCIe bus for awhile now though, 135mhz

Is that running SLI?

I got a hold of Corsair 6400C3 3-3-3-5 1T 808MHz memory and really got a boost in my 3D scores.
Later today I'll put the CPU on water and really start testing this motherboard and memories I have here.
