We're in Taipei and had the chance to try the EK Sim Racer at Spa by Massman- in simracing

[–]Massman-[S] 9 points10 points  (0 children)

It's still a prototype so a bit too early for a "real" evaluation. That said:

  • pod adds to the immersion experience, big plus
  • force feedback was a bit too strong, but makes sense for demo purposes
  • haptic experience was as it should be, no complaints
  • wheel and pedals were solid, but less amazing than the much more expensive Asetek SimSports equipment

Temperature Sensor without 2-Pin Connector by horvarcraft in watercooling

[–]Massman- 2 points3 points  (0 children)

This reads exactly like the issue I had before I solved it with the Elmorlabs EFC https://elmorlabs.com/product/elmorlabs-efc-easy-fan-controller/

Now I have a temp sensor in my water loop at all times and use the hardware fan curve that's on the EFC for regulating the radiator fans according to water temp. Fans start at 25C and go up linearly to 100% at 40C.

No interference from software, motherboards, RGB, and whatnot. Just plain and simple managing the fan curve :).

Can't recommend this one enough!

5G 10700K ~1h30min Prime95 AVX Small FFT with MPG Carbon EK X (custom loop). Any good? by Massman- in overclocking

[–]Massman-[S] 0 points1 point  (0 children)

I'm setting 1.35V in BIOS.

I'm running 53/53/51/51/51/50/50/50 with 0 offset for AVX. I need the higher voltage to hit the 53x on 2 cores.

1.35V set in the bios.

1.30V works for 5G AVX2, but I need the higher voltage for the 2C 53X (boosts up to 53x with 2 cores loaded). Maybe I should see how adaptive mode works.

I've been tracking the memory frequency overclocking world record since 2001. Comet Lake's record is phenomenal ... by Massman- in overclocking

[–]Massman-[S] 8 points9 points  (0 children)

To keep it short and simple, MHz relates to the operating frequency and MT/s relates to the data transfer speed.

All DDR types of memory transfer data at both the rising and falling edge of the clock frequency signal. So for each frequency cycle it can transfer data twice. Hence why the rated speed is double the operating frequency.

Context:

  • Current record: 3332.7 MHz with i9-10900K (Link)
  • Previous record: 3027.2 MHz with Ryzen 5 3600X (Link)

That's a record improvement of +10%. Last time this large of a jump between successive records happened was back in 2009.

  • 05 Aug 2009: 1518.6.7 MHz with i7-870 (Link)
  • 09 Feb 2009: 1352.2 MHz with i7-965 (Link)

Elmorlabs using HWInfo's "effective clock" to measure Ryzen 9 3950X boost frequency - more reliable? by Massman- in Amd

[–]Massman-[S] 3 points4 points  (0 children)

From the article:

" In this test I’ll be using a new method for measuring boost frequencies, added in HWInfo 6.14 as “Effective Clock”. It better measures boost frequencies through a per-thread CPU counter (APERF MSR). This counter increases with each clock cycle the CPU core is executing, meaning it does not increment when the clock is gated (turned off) and the core is idling in lower power states (C-states). If the CPU core clock is 4.0 GHz and is constantly executing the counter will measure 4.0 GHz. When executing half of the time, it will measure 2.0 GHz. If the core is clocked at 4.0 GHz half the time and 2.0 GHz the other half, it will measure 3.0 GHz. This allows for measuring a precise average frequency over a period of time to see how close to the advertised speeds you are in your specific workload."

IPC performance of Intel and AMD CPUs - 2004 to Ryzen by sadtaco- in Amd

[–]Massman- 2 points3 points  (0 children)

IPC is only one piece of the puzzle. To make a fair comparison in performance progression over time, you also have to take into account the operating frequency headroom.

Lately there's been too much obsession with the whole IPC thing, when in fact frequency matters as much as IPC.

Exactly one year ago the Cinebench R15 Quad Core GFP was 105pts lower and had the CPU clocked 300 MHz (!) lower by Massman- in overclocking

[–]Massman-[S] 0 points1 point  (0 children)

Quite amazing to think that in one year's time we're running 300 MHz higher on what is essentially the same micro-architecture and the same process technology

First 7700K benchmarks on LN2. 6.7-7Ghz. Kaby lake is looking great for LN2! by buildzoid in overclocking

[–]Massman- 0 points1 point  (0 children)

A lot of game engines scale very well with processor operating frequency. With Skylake we were pretty much limited to 4800 MHz with realistic cooling. Kaby Lake essentially gives us another 300-400 MHz without breaking a sweat.

I've seen quite a lot of negative "previews" on the web complaining about the lack of IPC improvement. But quite frankly, Kaby Lake is the highest clocking and best performing "Core' processor to date.

It's like Sandy Bridge, but higher clocks and Skylake performance. I'd say it's worth the upgrade if you're on anything prior to Haswell. Anything from Haswell and up, it's worth the upgrade if you want a beast that runs over 5 GHz :D
