Apple-B hit 2GHZ wall.

[bulk88]

I am still trying to overclock max out my locked K7 to mobile hack system. It will run stable at 18x100=1980. When I goto 19x110=2090 if the CPU is under load (distributed.net client, called dnet from now on) instant crash, if running prime95 instant error. This hasn't got anything to do with the multiplier changing, the prime95 and dnet clients run fine though any multiplier change except this one. I did a vcore boost from 1.5v to 1.75v via pinmod and no change. I am using a TR SK6+ with TT SMCF2 at full speed. I am using a syntax SV266AD MB. For details on which rig this is, look at my unlocking thread http://www.ocforums.com/vb/showthread.php?s=&postid=2445172 .

I am using a Duron 1.4 dhd1400dlv1c miuhb, 0347, upmw. It is a applebred B and I did hte mobile hack on it sucessfully.

that has to suck...

1.4 Ghz -> 1.98 Ghz..that's pretty good already..over 33% overclock. Probably AMD has speed binned the processor.

My Thorton 2400 won't go over 2 Ghz either..prime gets instant error and the whole system hangs.

I am using a really cheap MB. It has a 2 phase VRM. It only crashes the second I put a load on the CPU, so I am thinking power problems? am I right?

I'd say its a voltage regulation problem. With only a 2 stage vrm your asking for troubles. Compare that to an abit nf7 which uses a 4 stage vrm. a new mobo should be the next purchase for you.

i've tested 2 of of my stock so far and the 1.4 would go 1.8@ stock voltage-

and the 1.6 2.10 @ stock voltage-


both average 2.4 in the neighborhood of 1.85v although my board overvolts a lot-

but temps arnt to my liking @ those speeds on air-

watercooling these durons you'd prolly break some records-

I can't, got the board cause it was dirt cheap and new ($32 I think) and it has onboard lan:p. I can't buy a NF2 every time.:(

I think it is the power. I upped the voltage to 1.85v from 1.75. For this post load is prime95. Stable is no BSOD and no errors from prime95.

Before the mod 1980 was max stable with 1.75v, now with 1.85v it is atleast 2310 stable under load with temp at 41C, GAWWW :drool: Sweet!!!! (no offense to dell guy).That is better than the RIG in my sig at 2324 because I know I can go higher than 2310.

2380 generated prime95 errors. I wonder what this proc would do if I threw it in my NF7-S but that doesn't support powernow. :cry: I probably could hit 2450 mhz stable with 2.05v on AIR on that board. This is one GOOOOOD chip.

Currently I can hit 2400 with this chip but that isn't stable under load, so I could get a screen shot but the system is useless otherwise.

I am using a Duron Applebred-B 1.4 ghz, MIUHB, DLV1C, 0347upmw with a TR SK6+ and TT SCF2 at full speed.

Also is this a good overclock 2310@1.85v@41*C? Or can I go higher?

Whats also cool is this is on a GHETTO KT266A board (Syntax SV266AD). 8735 SB. 2 phase VRM. This board is effectivly a unoverclockable OEM board EXCEPT for the 1step MHZ adjuster. 2310 is 140x16.5. I dont care about the FSB and try to keep it as low as possible.

Keep checking newegg refurbs. I picked up an ASUS A7N8X Deluxe for 58(Sillicon RAID-0), ASUS A7V8X-X for 35 and a Gigabyte DXR7+(Promise RAID-0) for 28.

All with free shipping.
