AMD® Athlon™ II Overclocking Thread

iTek, that's a good point actually . . . I would say set the stick to DDR2-800 [1:2] in BIOS, drop processor multi to [x10] and drop both the CPU-NB/HT-Link multi to [x8] then change the HT ref. Clock from 200MHz to 266MHz . . .

2660/2128/2128/1064

That config will test the ram at it's stock speeds and also test the boards Ht ref. Clock . . . . good luck! :cool:
 
shouldn't that say (128 bits) for dual channel? (I can't remember?) does it say dual-channel is CPU-z? . . . . reset the system back to stock and test the memory with no overclock . . . . is it a faulty stick or is it a faulty slot?
 
Hello iTek . . . some progress I see! :)

You mentioned the "memory controller on the board" . . . This was moved from the NorthBridge and placed inside the AMD CPU some years ago . . . It's now called an Integrated Memory Controller (or IMC for short) . . .

As your making an effort to get some screenies up can I ask you make them similar to the results in post #2 with a two CPU-z windows open side-by-side, this makes it easy for anyone to see your current config! . . . also if you are able run some Prime95 *blend* for as long as you can then make a screenie of that . . . . if you click on the results in post #2 you can copy the layout for your stability screenies!

 
Can you lower the 3.5GHz vCore down any lower than 1.520v? . . . it may be the chip is just thirsty but I'm running a similar config at under 1.400vCore (1.392v) . . .

Here ya go iTek . . . . consider this a weeks worth of testing! :p

Hey iTek,

nice to see the progress you been making! :)

However . . . now you unlocked your latest chip to a Deneb you no longer meet the criteria for submissions to this thread :D

  1. Sargas
  2. Regor
  3. Rana
  4. Propus
Please post your results in the AMD® Phenom™ II Overclocking Thread . . . . (Welcome Post here) . . . keep up the good work! :cool:
 
Hey iTek . . . Propus has no L3 cache, only Deneb has that, it's different silicon and not really comparable with Propus in the strictest sense . . . it's all good though, looks like a great chip, now you just need to work out a way to achieve 308MHz HT ref. Clock and get a sniff of 4GHz! :D
 
Hey roadie, glad you enjoyed the thread :)

Yeah boards that can run 300+ HT ref. Clock do broaden the scope of the maximum overclock but I think a stable 4GHz is gonna be a big ask from a Propus die, did a little reading about the newer C3 revision but didn't spy anything technically significant in the change? . . . we will have to wait and see I guess! :cool:
 
So few AMD® Athlon™ II OverClockers?

Small update . . . . I treated myself to a dedicated GPU, bought used from OcUK MM for £35 collect . . . very pleased! :o

8800gtsgpuz03.gif


Obviously having been using the onboard Radeon HD 4200 this is like a"Godly" upgrade! . . It's only for a bit of Team-Fortress 2 and Half-Life 2 @ 1920x1200 . . . . cut to the chase after about 20 minutes gaming my overclocked PC crashed! :eek: . . . . sweet so reset to stock and problem goes away? . . . so my mega-primed/IBT/LinX overclocked system while using the onboard IGP suddenly becomes unstable when using a dedicated GPU?

I didn't have this issue when running an overclocked TripleCore + HD 4890 so had to think why a QuadCore + 8800GTS would cause a problem . . . as the system worked 100% stable at stock that ruled out any driver related business, I wondered maybe if the power-draw was to much for the Corsair HX520W I am using? . . . connected up a power-monitor brick to the system and fired up every resource hungry diagnostic I had for both the system and GPU and managed to get 307 watts? . . . that shouldn't be a problem for a decent 520 watt PSU right? . . . next step was to connect the PSU up to a dedicated PSU tester to see if there was any slight issues? . . . nope nothing! :D I like that because I bought that Corsair PSU used from OcUK MM (£45.00 inc) and have been caining it for 18 months solid and its still holding it down nicely! . . . props to Corsair for choosing good units to put their name to! ;)

Anyway so at this stage I still wasn't sure WTF was causing my game crashes :confused: . . . Dived into the BIOS to inspect the 3.5GHz (inc IGP)settings I've been using solidly the past few months, tried a bit more vCore but still crashed in games? . . . I then adjusted two settings that had previously been on [Auto] and got a good result

  • HT Over Voltage
  • GPU Overclocking
I wasn't sure if HT Over Voltage was referring to Ht ref.Clock or HT-Link? for the 3.5GHz overclock the Ht ref.Clock is 250MHz but the HT-Link can be either 2.5GHz with the default [10x] multi or 2.0GHz when using a [8x] multi, fact is the games crashed when either frequency was used so changing this HT Over Voltage from [Auto/1.2v] to manual 1.3v has totally fixed the game crashing issue! . . . this also kinda indicates that this specific voltage helps with getting an improved Ht ref.Clock (and not HT-Link) . . .

The other BIOS setting that was adjusted was this GPU Overclocking thing? . . . It had been on [Auto] while I was using the IGP but I wondered if maybe it was clashing with the nVidia GPU? . . . total longshot I know but I thought if I at least took it from [Auto] and set it to a manual value that may help the game crashes? . . . I shouldn't have really changed two BIOS values at the same time because now the problem has been fixed I'm not sure which value was the win! :p

I will make an update in a few days after I confirm this, I suspect it was boosting the HT voltage but I'll let you know when I'm totally sure . . . it's fixed no doubt as I've been gaming four hours every night and the system has been 100% rock solid!

Bit of a waffle but maybe this will help someone out one day! :cool:
 
Hey fozzybear,

What I would do in your boots is run CoreTemp* to get an idea of heat, quicky test the unlocked chip with a simple 20 loop run of LinX, if that passed give Prime95 "Blend" test a run between 1-4 hours . . . if that passes loop either 3DMark or similar 3D-application for an hour . . . this is basically a quick test to see if your unlocked core is stable(ish) . . .

If you *don't* encounter any errors or glitches then reset the unlock back to a Triple-Core, and run CINEBENCH 11.5, wPrime and 3D-Mark making a not of your scores . . . . then unlock the chip again and repeat the benchmarking process and compare the scores! . . .


*CoreTemp: Although there are mixed views of whether or not the temps readings from the app have any reflection on the actual processor temps I have used it as a rough gauge to note the difference between low and high, it's good enough to start with . . . . you wouldn't want to see temps above 50°C using this app . . .
 
If your looking at the right sensor then the CPU temp should be the same as the CPU temp from the BIOS . . . I'm still not sure if this is a sensor within the processor or a sensor in the CPU socket . . .

55°C from hwmonitor is ok I think bearing in mind your hammering the processor with a "synthetic" workload to represent the Worst-Case-Scenario and your unlikey to encounter a load like this in Real-Word usage like gaming etc . . . although apps that load all the cores like encoding will come close!

Are you using the stock cooler? . . . also are you using full [Auto] voltages? . . . can you list your relavant specs please?

  • Cooling
  • Mobo
  • PSU
  • etc
 
Hey fozzybear,

it has never been possible to get readings for each separate core with these chips . . . you may be thinking of Intel® Core™2 processors that had a DTS sensor built into each core!

Looks like from your basic testing the unlocked core is fairly stable! . . . nice one! :) . . . have a read of this thread from start to finish if you need more help . . . you may need better cooling if you decide to overclock bit . . . for now you seem good! :cool:

P.S@ check your trust email please!

am very impressed with the performance of this chip so far, when you factor in the £60 cost, it's great value.

Nice one Emlyn! :)

It's hard to get this message across . . . I mean it's a £60 processor . . . it can't be any good can it! . . . . I sat there scratching my head for days last Nov (2009) after "upgrading" from a Intel® Core™2 Duo E8400 @ 4GHz to an AMD® Athlon™ II X3 @ 3.6GHz and thought the AMD® was faster, ended up with nearly £100 more in my pocket after the upgrade . . . WTF! :confused:

I do love the IMC on these chips, it's AMD®'s special thing innit! :cool:
 
Nice one tankskun! :)

a 45watt TDP AMD® Athlon™ II X3 405E running a 22% overclocked in a cute mini-ITX . . . yum! :D


Click image for product page

Can I just ask, what exact memory are you using? . . . I'm looking at the [SPD] tab in your screenie and see Samsung but I can't be sure what its max rated speed is? :confused:

Over 2.9ghz is not stable.

Did you try to lower the HT-Link/CPU-NB multi down from [x10] to something lower like x9 or x8?
 
Hey 1979Damian :)

3.5GHz sounds good from a chip with just an x11 multi!

319 HT ref.clock is a nice result from your mobo . . . and you got a "free" extra core also! . . . very jammy . . . hope its stable! . . . enjoy! :cool:
 
Nice one jmp_78 :)

An AMD® Athlon™ II X2 @ 3.65GHz with a 1GB Radeon HD 4870 sounds nice for a HTPC! ;)

Get some stability/temps screenies up when you have time please! :cool:
